In the idiom list for the entry HELP, the following sentence has been categorised as wrong sentence-
He helps me in raking the leaves.
while the following sentence is correct-
His help in raking the leaves has been welcome.
Is there any difference in meaning between these two sentences?
Can we interchange AID with HELP ?
