I'd like to know which preposition should be used in the following examples:
This is for my family.
This is to my family.
Which one is correct?? How do I know when to use either TO or FOR ??
Are there books only about prepositions?
Thanks a lot
Welcome to the forums.
This gift is to my family = It is intended that this gift is given to my family.
The context will tell you which preposition to use.
Even native speaker have to learn by heart which prepositions to use! There are many sites which explain them and their use: prepositions - Google Search
