Questions & Answers about मेरे दाँत साफ हैं।
Because मेरे must agree with दाँत.
In Hindi, words like मेरा / मेरी / मेरे mean my, but they change form depending on the gender and number of the noun that follows:
- मेरा = for singular masculine nouns
- मेरी = for singular feminine nouns
- मेरे = for plural nouns (and also some masculine oblique contexts)
Here, दाँत is treated as masculine plural, so we use मेरे:
- मेरा दाँत = my tooth
- मेरे दाँत = my teeth
Because the subject is plural: दाँत = teeth.
In Hindi, है is generally used with singular subjects, and हैं with plural subjects.
So:
- मेरा दाँत साफ है। = My tooth is clean.
- मेरे दाँत साफ हैं। = My teeth are clean.
Not all Hindi adjectives change form.
साफ is an indeclinable adjective, which means it does not change for gender or number. It stays whether the noun is singular, plural, masculine, or feminine.
