Backing can also mean any material that is used to cover the back of something, e.g. a framed picture, an upholstered item etc. It can also refer to musical accompaniment as in 'backing singers'. I think there are one or two other meanings - one to do with theatrical scenery and the other an engineering term. 'Issue' can mean (as well as kwestia or sprawa) an issue of a magazine or newspaper a financial instrument or a banknote, stamp or coin. It can mean someone's children as well as geographical, legal and medical meanings.

Maybe, but we don`t do such unimportant stuff in class. :):):):):)

Backing singers or a backing group is quite common really!

When "backing" groups are mentioned, students prefer support. Or backup

PS. Contemporary youth hate singing.

A shame, since it opens the neural doors to so many other skills. Useful for language acquisition too!

and backup is what police call for.

And a band who are supporting another band come on stage before them and don't usually do the backing!

Yes, I agree, but Poles have always been reluctant to sing when sober. Some don`t even know the text of the Polish anthem.
