Adjectives
   

An adjective is a word that modifies a noun. In Persian, the adjective normally follows the noun it qualifies:

(a/the) good book ketāb-e xub کتاب خوب
(a/the) big/great man mard-e bozorg مرد بزرگ
(a/the) small room otāq-e kucak اتاق کوچک

The attributive adjective is not pluralized along with the noun it qualifies:

good book ketāb-e xub کتاب خوب
good books ketāb hā-ye xub کتاب های خوب
big/great man mard-e bozorg مرد بزرگ
big/great men mardān-e bozorg مردان بزرگ
small room otāq-e kucak اتاق کوچک
small rooms otāq hā-ye kucak اتاق های کوچک

It is possible to have more than one adjective qualifying a single noun. In this case the noun and its multiple adjectives are linked by the means of the ezāfe construction.

Unlike English, there is not a fixed order in the usage of multiple adjectives:

خانهٔ بزرگ نوساز سفید
xāne-ye bozorg-e nowsāz-e sefid

خانهٔ سفید بزرگ نوساز
xāne-ye sefid-e bozorg-e nowsāz

خانهٔ نوساز سفید بزرگ
xāne-ye nowsāz-e sefid -e bozorg

All of which mean, ‘the big, newly-built white house.’

However, some attributes are so hierarchical that some sort of priority and order is observed. Between the following two sentences the former is preferred to the latter:

مردی دانا و بزرگ
mardi dānā va bozorg
‘a knowledgeable/wise and (a) great man’

مردی بزرگ و دانا
mardi bozorg va dānā
‘a great, wise man’

That is because a man becomes knowledgeable and wise first and (only) then he becomes great.
