One common way of expressing multiple entities is to use numerals and quantifiers such as many, too_many (see [Syntax – 4.4.] and [Lexicon – 3.10.2.]). Another common way is to use classifiers (alone or together with the nouns) ([Morphology - 5]) which can be reduplicated or morphologically modified to include path or circular movements to express plurality.
As for the plural inflection of nouns themselves, TÄ°D does not have a productive way of inflecting all nouns for plurality, hence, it does not have a plural affix.
