Which is the right expression?:
"Change the channel" or "change channels" ?
"Change the subject" or "change subjects" ?
If I say "oh please, change the channel!" or "Let's change the subject!" is it ok?
If you are interested in using THE, then the answers would depend on the situations.
If someone asks you an embarrassing question, just change the subject. This term uses subject in the sense of "a topic of conversation.
To change the channel is to switch to some other topic of conversation.
Let's change the channel here before there is a fight.
In that case I would not say "the group" but "groups." Or maybe "change my group."
