I was reading a poster recently which stated:
Babies love skin on skin – can't you tell?
And I realized that while this is perfectly grammatical, if I were to now replace
can not (which is the non-abbreviated form) it would no longer be so:
Babies love skin on skin – can not you tell?
I found this interesting because generally it would be fine to use the non abbreviated form, see the following for example:
I can't tell
I can not tell
Which is just fine.
Babies love skin on skin – can't you tell? a valid usage of the word
can't? Why is this?
