See what I'm saying? (3-4)

I believe the answer is:

lip-read

I'm a little stuck... Click here to teach me more about this clue!

'see' is the definition.
(I know that lip-read is a more specific form of the action read)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for lip-read that I've seen before include "Understand by watching mouth" , "Interpret someone''s words when deaf" , "Understand without hearing" , "How to "hear" when deaf" , "Dire pal can interpret mouth movements as words" .)

I've seen this clue in The Times.
