Language/Urdu/Grammar/Adjectives

Like those in English, Urdu adjectives describe nouns and thus are a crucial element of Urdu grammar. Let’s have a cursory look at the nature and function of Urdu adjectives.

The first thing that you must learn is that the gender of an adjective is determined by the noun:  

• گہرا دریا (gehra darya) – “deep river”
• گہری نہر (gehri nehar) – “deep canal”

In the first example, the adjective گہرا (gehra) is used in masculine form because the noun دریا (darya) is masculine. In the second example, the adjective گہری (gehri) is used in feminine form because the noun نہر (nehar) is feminine. Thus, you can see how Urdu adjectives must agree in gender with the noun they describe.

Also remember that Urdu adjectives are normally placed before the nouns they describe.
