i don't understand very well english (i am trying to learn :) ), what i see in the question 2 words, what and for, it means that we are gratful to someone, for something (it is my understood, i hope i am right ..)
i am gratful to allah the merciful for all what he gave me, and what he gave for all humans, and if we do a list it wil not finish, but i am gratful to my mother who etudated me and suffere a lot to make us grow up and for caring and tenderness, and for my teachers from a primely school until university (not for all ..), and for all perosns who told me a day a nice word or smiled me :)
