Here's where you get stuck! (5)
I believe the answer is:
glued
'stuck' is the definition.
(I've seen this in another clue)
'here's where you get' is the wordplay.
'here's where' becomes 'gled' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'you' becomes 'u' (commonly used in online communication).
'get' means one lot of letters goes inside another.
'gled' placed around 'u' is 'GLUED'.
Can you help me to learn more?
(Other definitions for glued that I've seen before include "Stuck together" , "Gummed" , "Stuck one thing to another" .)
