Inversion

got it ;)

Inversion form - verb + sub
when we need to write inversion, we have to switch the position of verb and subject. If verb is verb to be, it is no problem we put verb to be in front of the subject.
If verb to do, we have to change do,did,does according to the tense.
:-D:-):lol:
That is all i know
If there is any mistake, everyone can correct it!!!:oops:

Shit, I got it wrong:oops:

same as thread NOT UNTIL. A negative element at the beginning

only, seldom, rarely, few, little ... verb - subject

Little CAN HE do for me

because LITTLE means NOT MUCH.

Inversion is used when a negative element precedes:
only, seldom, few, little, not, never

Only when did i arrive...
