Would you please explain the use of to infinitive and to, as a preposition, + gerund, and when do we use one over the other? Many times, I have a problem deciding whether to use a regular to infinitive or treat the "to" as a preposition and add an
-ing to the verb to make it gerund. I've gathered some sentences using
to + gerund below:
- It is an approach to obtaining.....
- It is a key to making.....
Other than "key/approach/committed/dedicated
to +ing," could you guys think of other words?
