I believe the answer is:

extricate

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

'get out' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for extricate that I've seen before include "Get free from" , "Free (someone) from difficulty" , "Disentangle, set free" , "wriggle free" , "Free (something) from difficulty" .)

I've seen this clue in The Irish Times.
