As a general rule, the plural of a noun is made by
adding -s to the singular: can (dog) > dogs (dogs); boira (cloud)
> boiras (clouds).
The same rules are to be applied to adjectives:
choben (young) > chobens; gran (big) > grans; feble (feeble) > febles.
When the singular ends en -r the general rule
is followed, but the "r" doesn't sound: flor (flower) > flors (flowers
[pronounced /flos/]); muller (woman) > mullers (women); fener (lawn) >
feners (lawns).
Words ending in -ero form their plural
in the same way and the "r" is not pronounced either: cordero (lamb) >
corders (lambs [pronounced /kor'des/]); minero (miner) > miners (miners);
comprero (purchaser) > comprers (purchasers).
Words ending in -t, -d or in a
stressed
vowel (as a result of a final -t or -d dropped) form their plural by
changing the last consonant to -z (or adding this -z to the stressed
vowel): ziudá (town) > ziudaz (towns); pie (foot) > piez (feet);
mozet (youth) > mozez (youths); purput (hoopoe) > purpuz (hoopoes).
Among these words we can find all the diminutives
ending in -et (masculine), a very productive ending in present Aragonese:
canet (little dog) > canez; libret (booklet) > librez.
Words ending in -ch, -x, -z,
-s
form their plural by adding -es: reloch (watch) > reloches (watches);
pex (fish) > pexes (fish, fishes); zorz (mouse) > zorzes (mice); aragonés
(Aragonese) > aragoneses.
Certain words are always plurtal: balons (trousers),
beires (glasses), diners (money), estixeras (scissors).
And some compounds are singular in spite of their
plural appearance: bateaguas (umbrella), birabolas (butterfly), pasariestas
(sieve).
