Hello

I am designing a cloze activity on an Aussie football song and it has �em all the way through it, meaning them.

I �m not sure, but is this theoretically classified as a contraction for informal spoken speech or is it something else.  Is there anyone who is an expert in this area?

e.g. In there and at �em, don �t let �em in

Thanks

Cheers

Jayho
