Hello, could you tell me if this structure is possible.

I looked it up in Longman on line dictionary and in the Collins but I found no answer. Thank you.

How does this sentence sound to you?

"He used them for begging in the streets"

Thank you.
Soprano"He used them for begging in the streets"
It's fine. "Them" can refer to beggar's bowls (kashkuls).

Students: Are you brave enough to let our tutors analyse your pronunciation?
Thank you.

But I know what he was refering to...

He was refering to kids.

He used the kids for begging in the streets.

Is the usage fine anyway?

Thank you again
Using the kids isn't fine, but grammatically speaking, the sentence is.
