Bothered by son getting caught (7)
I believe the answer is:
snagged
'caught' is the definition.
(snagging is a kind of catching)
'bothered by son' is the wordplay.
'bothered' becomes 'nagged' (to nag is to bother continually).
'by' means one lot of letters go next to another.
'son' becomes 's' (genealogical abbreviation for son).
'nagged' put after 's' is 'SNAGGED'.
'getting' is the link.
(Other definitions for snagged that I've seen before include "Caught on a sharp projection" , "Unexpectedly held up" , "Caught on jagged projection or in unexpected difficulty" .)
