You can also say " Hum dilli jaya karte the" = Hum dilli jaate the.
Hum pehle delhi jate the
This should be correct.
Y is Hum Delhi jathe thi wrong .
Thi is féminine singular. 'thy'/थे is pural. Since the sentence starts with "we" tou need to use pural terms.
What's the difference between "jaate the" and "gaye the"?
"gaye the" is like we went there once while "jate the" connotes the sense of we used to go there regularly.
Gaye the ka matlab ek bar, or jate the matlab pehle bhi ja chuke hai...
Jaate the. It shows habit
This is wrong....it should be " hum pahle Delhi jate the"... because it said We "Used" to go to Delhi.
