In English one of the ways to determine if a word is a noun is to see if it has a plural form. This does not work with uncount nouns so another useful indicator is to see if the word or phrase has a definite or indefinite article. This suggests that in Diinlang a phrase can be made plural by pluralizing the article rather than the noun or noun phrase.
One objection to such a system is that articles may be dropped. Consider an exclamation such as “Dogs!” A single, pluralized syllable conveys the presence of dogs and that there is more than one.
If a number or quantifier is used in place of an article it may be argued that pluralizing the noun may be redundant. A sentence such as “Five chicken ran” can be ambiguous without background context. It could mean five chickens were running but might also indicate a particular chicken with the name or number “five”. The option of pluralizing the noun can clarify the meaning.
In Diinlang it might be said that plurals are formed by article form and/or with a noun suffix. In some languages article and noun are required to agree. If an article is plural the noun should be a plural form too. In Diinlang this is unnecessary and redundant. It should not be considered to be incorrect, however. The variations in pluralizing will suit users of different native language backgrounds or may improve the euphonics of a phrase.
Often in Diinlang there is more than one correct way to say something. The objective is to promote communication and clarity rather than observance of unnecessary rules.
Plurals are formed in Diinlang by adding “-z”. For words that end in a sibilant such as “s” “-iz” is used instead. Thus “Dogs!” could be translated as:
It is unnecessary to pluralize a noun if the noun is accompanied by a plural form of pronoun, article, determiner, numeral or quantifier. If a noun has a plural form of gender prefix ( zoz-, zaz-) it is also obviously plural. If a noun does not have an article etc it can be pluralized by adding the neuter equivalent of the plural gender prefix.
Hence, “zez-kanis” = “dogs”.
