dances q laga she ke sath

kyunki yeh rule h, simple present tense me I, We, they, you or plural (ek se zyada) ke sath verb ki first form lagti h.. example - I wake up early in the morning. aur he, she, it or singular(ek) ke sath verb ki first form k sath 's' ya 'es' lgta h. example - he wakes up early. she likes chocolates. Mohini goes to walk daily.

Because "she" is third person singular pronoun and for a singular subject, we use a singular verb. So, to make any main verb singular, we add "s/es" end of that verb.

Because, "She" is 3rd person singular number, So we use "s" after the main verb (dance). Ex :- He dances. It eats. You dance.
