Since you might have in inability to decipher the code that an āsā at the end of a word forms, here you are.
In linguistics, plurality or [a] plural is a concept of quantity (i.e., grammatical number) representing a value of more-than-one. Typically applied to nouns, a plural word or marker (morpheme) is used to distinguish a value other than the default quantity of a noun, which is typically one. Plurality is a linguistic universal, represented variously among the languages as a separate word (free morpheme), an affix (bound morpheme), or by other morphological indications such as stress or implicit markers/context.
In the English language, singular and plural are the only usual grammatical numbers, with minor dual exceptions (ābothā, āeitherā, etc.)
A plural is commonly abbreviated pl. in dictionaries. In part-of-speech tagging it has other notation which distinguish different types of plurals based on the grammatical and semantic context.
In English, the plural is usually formed with the addition of -s (e.g., one cat, two cats; one chair, two chairs) or -es (e.g., one bush, two bushes; one itch, two itches). Generally, -s is added to all nouns that end in a voiceless consonant, vowels, or voiced non-sibilants, whereas -es is added for nouns ending in a sibilant sound. Nouns that end in e are a noted exception; though e may form a sibilant sound, -s is used (e.g.,. one tree, two trees; one bee, two bees).
Some plural forms require more noticeable changes in word structure. Most words ending in a y preceded by a consonant are pluralised with ies (e.g., one lady, two ladies; one cherry, two cherries). Some words ending in f are pluralised with -ves (e.g., one leaf; two leaves; exception: one roof; two roofs). Words ending in x are often pluralised with -ces (e.g., one matrix, two matrices; one index, two indices). Words ending in us often replace the us with -i (e.g., one cactus, two cacti; one fungus, two fungi). A subset of words ending in um or on are pluralised by replacing with -a (e.g., one forum, two fora; one criterion, two criteria).
Other variations occur where vowels and consonants change in the middle structure of the word. Such examples are, (1 die; 2 dice), (1 goose; 2 geese) and, (1 mouse; 2 mice).
A small class of words have identical singular and plural forms: e.g., one sheep, two sheep; one aircraft, two aircraft.
