Plural inflection methods for the English-language Linguistics module.
It provides conversion of plural forms of all nouns, most verbs, and some adjectives. It also provides “classical” variants (for example: “brother” -> “brethren”, “dogma” -> “dogmata”, etc.) where appropriate.
Classical “..a” -> “..ae”
Classical “..a” -> “..ata”
Classical “..en” -> “..ina”
Classical “..[ei]x” -> “..ices”
Arabic: “..” -> “..i”
Hebrew: “..” -> “..im”
Classical “..o” -> “..i” (but normally -> “..os”)
Classical “..on” -> “..a”
Classical “..um” -> “..a”
Classical “..us” -> “..i”
Classical “..us” -> “..us” (assimilated 4th declension latin nouns)
Unconditional “..a” -> “..ae”
Unconditional “..[ei]x” -> “..ices”
Unconditional “..man” -> “..mans”
Always “..o” -> “..os”
Unconditional “..on” -> “a”
Unconditional “..um” -> “..a”
Unconditional “..us” -> “i”
