Getting stuck, Charlie has a breather (5)
I believe the answer is:
clung
'getting stuck charlie has a breather' is the definition.
I can't judge whether this definition defines the answer.
'charlie has a breather' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' is a charade indicator (letters next to each other).
'a breather' becomes 'lung' (I've seen this before).
'c'+'lung'='CLUNG'
(Other definitions for clung that I've seen before include "Was emotionally close" , "Held on desperately" , "Held on tightly" , "Held on tight" .)
