User:Qehath/Appendix:Persian ordinal numbers

For the most part Persian ordinal numbers are formed quite regularly, with a limited number of irregularities, with the suffixes (which is less formal) and  (which is more formal). There are only a few differences in usage between these forms. For example, the more formal forms precede the nouns they modify, like superlative-form adjectives, and the less formal  forms follow nouns with ezâfe. For example, "fifth night" could be rendered in either of the following two ways:

Fractionals (such as two thirds or three fifths) are formed in precisely the same manner as in English: with a counting cardinal number and an ordinal number. For example, the examples used previously, two thirds and three fifths, would respectively be undefined: and undefined:. Note that forms are not used in expressing fractions, only.

Some more robust examples are:
 * undefined:,
 * undefined:, and
 * undefined:.

Further, as in English, some fractions have special terms.
 * half - ,
 * third -
 * quarter -

and are not entirely interchangeable. uses ezâfe and is not always translated as "half". For example, undefined: translates as "the middle of the night". However, undefined: does translate as "half the book". Thus, "I read half the book" would be undefined:.

Meanwhile, is used more for quantities, amounts and more strictly numerical concepts. undefined: is a half-hour, undefined: is a half-kilogram, etc. Expressions such as "one and a half" also use.
