Tundrian nouns and adjectives are declined for number and case. There are two numbers: singular and plural. There are two cases: nominative and accusative. It should be noted, however, that in nouns and adjectives (as opposed to the definite article and the demonstrative adjective) the distinction between nominative and accusative is only made in the plural .
The basic rule for the use of the cases is given below.
  • The nominative is used in the following situations:


    • For the subject of the sentence:

      • Mêi amiyci son devêniyti campioni. My friends have become champions.
      • Cel livro se volverá el melhour livro del seyl. This book will become the best book of the century.
      • Xempre restará la mîa poriyna. She will always remain my little girl.


    • When in apposition to another noun in the nominative case:
      • Celi prêsidenti, touti Dêmocrati, han favorizat los syndicats. These presidents, all Democrats, have favoured the unions.
      • Ella deveine Catherina, la plus grand tzariyna rûssa. She became Catherine, the greatest  Russian Empress.


    • In temporal absolutive constructions:
      • El ân xequent, mî amiyc me visitó denôu. Next year, my friend visited me again.


    • In titles, addresses and other stand-alone expressions:
      • La guerra ê la paç. War and Peace.
      • La Casa Blanca, Washington. The White House, Washington.


    • When in any of the syntactical situations above and preceded by the numerical qualifiers circa (about), min que (less than, fewer) or plus que (more than):
      • Circa dzeç enfanti son vêniyti a lâ festa. About ten children came to the party.
      • Min que mil persoune han votat por nostro candidat. Fewer than a thousand people have voted for our candidate.
      • Elli son plus que treis mil a participar. They are more than three thousand to participate.
      • Son li magnífici, li circa dzeç compositouri qui dóminan lâ música clâssica. They are the magnificent ones, the roughly ten composers who dominate classical music.

      • Li caini morsuron lâ vûlp. The dogs bit the fox.
      • La javuta si ha frait lo brâç. The girl has broken her arm.


    • For the complement of a preposition (except circa, min que and plus que):
      • En lâ isla vi havîa es centans de soldats japoneisos. On the island there were hundreds of  Japanese soldiers.
      • Ha dat lo dinêr a los amiycs de sû fraire. He has given the money to his brother's  friends.
      • Cel livro fu escrut per lo autour cêleur de scientza-fictzoun, Robert Heinlein.  This book was written by the famous science-fiction author Robert Heinlein.


    • When in apposition to another noun in the accusative case:
      • Dé los livros al Rey Joân, lo Bón. He gave the books to King John, the Good.
    • When in any of the syntactical situations above and preceded by the numerical qualifiers circa (about), min que (less than, fewer) or plus que (more than):

    • mur / muri (wall), taur / tauri (bull)
    • programma / programmi (program); homne / homni (man); imagë / imagi (picture); pauvro / pauvri (poor [m.])
  • Normally, the ending is -s added on to the sing. form: mur/ murs, homne / homnes. In the comments below, the is only mentioned when its formation involves more than just the addition of -s (with or without a supporting vowel).
  • The of Class B nouns and adjectives needs a supporting vowel in certain cases, which are outlined below. This supporting vowel is as follows:
    • Feminine forms always take -e-: tûrres (towers), capaces (capable).

    • In invariable adjectives (i.e. adjectives that do not change in the feminine) requiring a supporting vowel in the, this vowel is always -e in both genders: capaces (capable), tristes (sad).

      • However, those ending in consonant clusters whose second component is -d, -t or -th do not need a connecting vowel, as the -s of the accusative merges with the dental stop into an affricate (i.e. a single consonant phoneme): bord / bords (seashore), fort / forts (strong), hyacinth / hyacinths (hyacinth)]
    • -st, -xt: cost / costos (cost), sext / sextos (sixth)
    • -ct, -pt: act / actos (act), rapt / raptos (abduction)

    • -oil / olli: coil / colli (hill; neck), moil / molli (soft)
    • -ûil / ûlli: pûil / pûlli (chicken)

  •  Nouns and adjectives ending in -am, -án, as well as monosyllables ending in -an, generally change the -a- to -ai- in the

      • However, nouns and adjectives ending in -án that denote the name of a people, religious group or language change the -án to -ani  in the, without the diphthong. Some examples: amêricán / amêricani, christián christiani, êgiután / êgiutani (Egyptian), italián / italiani, tundrián / tundriani. Also belongs here: ôceán / ôceani (ocean)
    • The of all these forms is regular, except that the acute accent is not necessary: antzans, capitans, çutans etc.

  • Nouns and adjectives ending in -ábil, -íbil and -óbil  lose the -i- of the last syllable in the, and as a result do not need the acute accent:
    • -ábil: agratábil / agratabli (pleasant), potábil / potabli (drinkable), responsábil / responsabli (responsable)
      • Exception: hábil / hábili (clever, able)

    • -óbil: nóbil / nobli (noble)
      • But: móbil / móbili (mobile) is regular

  • Nounds ending in unstressed -er lose the -e- of the last syllable in the, and as a result do not need the acute accent: cadáver / cadavri (corpse), paláver / palavri (worthless talk).

  • Stress always remains on the same syllable during the declension of Tundrian nominals. Because of the peculiar rules that apply to the accentuation rules of words ending in vowel + n/s (and of some monosyllables ending in -ór ), accents may therefore appear in just the singular or just the of certain nominals. Examples of various patterns:
    • ending in unstressed vowel + n:
      • carpen / cârpeni (hornbeam tree), platan / plátani (plane tree)
      • destin / dêstini (destiny), termin / têrmini (terminus, terminal)
      • origen / orígeni (origin)
      • abdomen / abdómeni (abdomen),  orden / ôrdeni (order), organ / ôrgani (organ), orphan / ôrphani (orphan)
      • The same changes occur in the cârpens, plátans, dêstins, orígens, abdómens, ôrdens, etc. 
    • ending in unstressed vowel + s:
      • atlas / âtlassi (atlas), lapis / lápissi (pencil)
      • arquiris / arquírissi (rainbow), iris / írissi (iris)
      • The same change occurs in the âtlassos, lápissos, arquírisses
    • ending in stressed vowel + n (those ending in stressed -an or -án have already been dealt with):
      • bén / beni (goods), gén / geni (gene), hyphén / hypheni  (hyphen)
      • alfín / alfini (bishop [in chess]), domín / domini (range), magazín / magazini (magazine), pingüín / pingüini (penguin)
      • avión / avioni (airplane), bón / boni (good), campión / campioni (champion), hormón / hormoni (hormone), pión / pioni (pawn), són / soni (sound), tzón / tzoni (insane)
      • alcún / alcuni (someone), común / comuni (common), dejún / dejuni (breakfast), necún / necuni (none, no-one)
      • As the accent is no longer necessary in the either, it is deleted there as well: bens, alfins, avions, alcuns, etc.
    • ending in stressed vowel + s:
      • abús / abusi (abuse), excús / excusi (regret), intrús / intrusi (intruder)
        • Note the doubled -ss- in metús / metussi (same)
        • Note the doubled -ss- and the kept accent in: ânanás / ânanássi (pineapple), matrás / matrássi (mattress)
      • For all these nominals, the form follows the same pattern as the abusos, metussos, ânanássos
    • ending in -ór:
      • cór / cori (heart), lór / lori (parrot), sór / sori (sister, nun)
      • Same for the cors, lors, sors.

  • A few nouns and adjectives ending in consonant + s in the singular carry a circumflex over their stressed vowel (a, e or o) in order to indicate the correct pronunciation. In the this is no longer necessary, and the circumflex disappears. Examples:
    • â : escârs / escarsi (scarce), fâls / falsi (false), fârs / farsi (stuffed), gâns / gansi (gander), mâns / mansi (tame)
    • ê : divêrs / diversi (diverse, various), pêrs / persi (dark [of colours]), sêns / sensi (sense), univêrs / universi (universe), vêrs / versi (verse)
    • ô : côrs / corsi (Corsican), môrs / morsi (bit [of bridle])
    • The of these nominals follows the pattern of the escarsos, diversos, corsos, etc.
  • The use of the circumflex to indicate the correct pronunciation of some words, and the associated avoidance of doubled consonants in final position (except for -rr, -ss), are behind the following patterns:
    • â : ân / anni (year), attâc / attacqui (attack), brâç / bracci (arm), cât / catti (cat), crystâl / crystalli (crystal), sâc / sacci (bag)
    • ê : arquêt / arquetti (bow [for arrows]), bêl  [bef.vowels] / belli (beautiful), colonêl / colonelli (colonel), interês / interessi (interest), jêt / jetti (jet), tirêt / tiretti (drawer)
    • î : esmerîl / esmerilli (falcon), xîc / xicci (dry), xîn / xinni (meaning, sense)
    • ô : côl / colli (mountain pass), crôc / crocci (bishop's crook),  escrôc / escrocqui (swindler), pôt / potti (pot), sôc / socci (hoof), xôc / xocqui (bump, shock)
    • Mostly, the of these nominals is regular. However, if a supporting vowel is necessary, the circumflex accent is deleted and the consonant is doubled. E.g.: âns, arquêts, esmerîls, côls; but: bracços, interesses, etc.

  • There is no doubling of the consonant in the after a vowel with a circumflex when the consonant is r, and in a few other words. The circumflex is retained in the of these words. Examples:
    • with r: alviêr / alviêri (beehive), calcêr / calcêri (shoe), miratôr / miratôri (mirror), sôr / sôri (father-in-law)
    • others: parallêl / parallêli (parallel), raîç / raîci (roots), smôg / smôgui (smog);  also, in words of Greek origin, such as the following: amphytriôn / amphytriôni (guest), côn / côni (cone), iôn / iôni (ion), têlephôn / têlephôni (telephone)

  • With a few exceptions, there is no doubling of the consonant in the when the preceding vowel is û. In additon, the vowel never loses its circumflex. Examples:
    • No doubling: bûc / bûci (he-goat), crûç / crûci (cross), grûp / grûpi (group), jûg / jûgui (yoke), lûp / lûpi (wolf), nûç / nûci (walnut), tûb / tûbi (tube, pipe), vitûl / vitûli (hoodlum)
    • Doubling: bûs / bûssi (bus), tûn / tûnni (tuna fish)
  • Nouns and adjectives ending in -âu, -eu, -éu, -êu, -îu and -ôu have somewhat irregular nom. plurals:
    • -âu / -avi: câu / cavi (cave, basement; hollow), clâu / clavi (key, spanner), esclâu / esclavi (slave), grâu / gravi (grave, serious), nâu / navi (ship)
    • -eu (-éu) / -avi: breu / bravi (brave), calhéu / calhavi (pebble), cleu / clavi (nail [tool])
    • 3 nominals in -êu / -evi: blêu / blevi (blue), lêu / levi (light [adj.]), nêu / nevi (mole, birthmark)
      • But most nominals in -êu have -êi in the aerêu / aerêi (aerial), dzêu / dzêi (god), escarvêu / escarvêi (cockroach), europêu / europêi (European), judêu / judêi (Jewish, Jew), mêu / mêi (mine [pn.]), musêu / musêi (museum), nûclêu / nûclêi (nucleus), trophêu / trophêi (trophy), etc.
    • -îu / -iyvi: vîu / viyvi (alive)
    • -ôu /- ovi: bôu / bovi (ox), nôu / novi (new), sarcôu / sarcovi (coffin)
    • All these have regular acc. plurals (except for the loss of the acute accent in calheus): câus, breus, blêus, aerêus, vîus, bôus, etc.

  • Adjectives ending in -û after consonants other than g have their in -ui:
    • continû / continui (continuous [m.]), sûperflû / sûperflui (superfluous [m.]). The is regular: continûs, sûperflûs.
  • In a few words of Italian origin, used in the plural only, the accusative plural is -is rather than the expected -s: spaghetti [], spaghettis []; canelloni / canellonis.


  • In this class, the nom. and acc. plural are identical, ending in -s: ley / leys (law), Papa / papas (Pope). There are few irregularities.
    • One set of irregularities is in nouns ending in -óu, which lose the accent in the plural (because it is no longer needed to show the irregular stress), as in: bambóu / bambous (bamboo), bijóu / bijous (jewel), cangaróu / cangarous (kangaroo)
    • If a word ends in a digraph vowel that is unstressed, the stressed vowel must acquire a written accent when the -s of the plural is appended: bonsai / bônsais (bonsai), hindou / híndous (Hindu).
