Words like in, on, at, with, to, for are called prepositions. We use prepositions after many verbs, for example:
I went to London yesterday.
However, many learners use prepositions when no preposition is required.
Here are some examples of these mistakes:
TYPICAL MISTAKE: *I’ll call to you tomorrow.*
TYPICAL MISTAKE: *I meet with my boss every day.*
TYPICAL MISTAKE: *I contacted with him yesterday.*
In English, these verbs are normally used without prepositions:
I’ll call you tomorrow.
I meet my boss every day.
I contacted him yesterday.
Here are more verbs that we use without prepositions:
We discussed the problem. (NOT: discussed about the problem)
Angela divorced her husband. (NOT: divorced with her husband)
I answered his message. (NOT: answered to his message)
I’ll phone you tomorrow. (NOT: phone to you)
