More docile sailor kidnaps me (5)
I believe the answer is:
tamer
'more docile' is the definition.
('tame' can be similar in meaning to 'docile')
'sailor kidnaps me' is the wordplay.
'sailor' becomes 'tar' (tar is a kind of sailor).
'kidnaps' means one lot of letters goes inside another (I've seen this in other clues).
'tar' placed around 'me' is 'TAMER'.
(Other definitions for tamer that I've seen before include "less offensive?" , "Animal trainer" , "Less wild" , "Less arousing, exciting" .)
