how the future forms of the verbs are written in devanagari - karungo. karenge. jaunga. ayege. thank

Question

Answer

These verb forms imply future tense only

karunga - करूंगा (male says -I will do)

karenge - करेंगे (masculine plural subject - 'will do')
jaunga - जाऊंगा   (male says -I will go)
ayenge. -आएंगे (masculine plural subject - 'will come')

tha - था is masculine singular verb for 'to be'. it depicts past.

if standalone in a sentence, it means 'was'.
if used in past participle sentences, it can be understood as "had been".
