[Grammar] leaked information began circulating

[Oceanlike]

(A): Several days later, the leaked information began to circulate on the Internet.

(B) Several days later, the leaked information began circulating on the Internet.

In (A), 'began to circulate':
- 'began' is the verb?
- 'to circulate' is ?

In (B), 'began circulating':
- 'circulating' is?

I am learning parts of speech.
Thank you for teaching me. :-D

This goes a little bit into technical English grammar.

Here, (A) "began" is a verb and "to circulate" is an infinitive. (B) circulating is a gerund.

I know the terms but I am not an English teacher. You could wait for someone else with more knowledge about infinitives and gerunds to chime in or you could google the terms. There are a lot of resources out there.

I wonder if there is any difference between the two sentences, written in (v + infintive) or (v + gerund). It seems both are grammatically correct. Are they?

Thank you!
