I find that I have problems asking questions about parts of speech. Japanese tend to have problems understanding what I say. It's not like I can add square brackets in speech, and って doesn't seem to cut it either.

e.g.
「しては」って、してはいけないしか限らないの？

How can I make myself better understood in confusing sentences like this? Are there better ways to rephrase stuff like this?
