Experienced some loose ends (4)
I believe the answer is:
seen
'experienced' is the definition.
(I've seen this in another clue)
'some loose ends' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'SEEN' is hidden in the letters of 'loose ends'.
(Other definitions for seen that I've seen before include "Sighted" , "Distinguished" , "Witnessed" , "Met - understood" , "Perceived by sight" .)
