It is nice of you It is nice to you It is nice from you
However, we could say:
- It is (so) nice to hear you. - It's nice to hear your voice (again). - It's (so) nice to hear from you after such a long time. It is nice to hearing you. It is nice to hearing from you.
>> We do not use present continuous tense when we are stating a fact or general truth. It is correct to use simple present tense.
>> The present participle of the verb (ending in -ing) should not be preceded by the infinitive marker to, and after the infinitive marker to you should always use the base form of the verb. So it should always be Nice to hear and never Nice to hearing.
If you intend to use the verb hearing, you could say:
- Nice hearing from you (again). [informal] >> This is quite common in email, phone conversation, or regular talk. _
>> There is also a difference between to hear and to hear from.
The verb to hear just means that you can literally hear and understand what the other person is saying.
The phrase to hear from means to start or renew a social relationship with someone. In this case, you're trying to say that it was nice to speak with someone again, and you're not focusing on the physical act of hearing, so you want to say "Nice to hear from you".
To be hearing/imagining/seeing things (informal) Meaning: to think you are experiencing something that is not really happening.
I'm sure I saw my glasses on this table, but they're not here now. I must have been seeing things. Tenho certeza de que vi meus óculos nesta mesa, mas eles não estão aqui agora. Devo estar vendo coisas.
No doubt you're surprised to be hearing me. Aposto que está surpreso por estar me ouvindo.
No doubt you're surprised to be hearing from me. Sem sombra de dúvida, tu estás surpreso em ter notícias minhas. -
The preposition "to" can be part of prepositional phrases or infinitive markers.
I hope you enjoy your studies.
