help me (to)
do
Hello,
Could someone explain to me when we add "to" in this phrase:
he help me (to).
Could we say:
More saliva, in turn,
helps them (to)
feel fuller.
John
helped me (to) do my homework.
She did everything to
help her son (to)
succeed in life.
Is there a specific grammar rule that tells us when to use "to" after "help me"?
Thank you!
