Maybe canines in part of golf course on Thursday (5)
I believe the answer is:
teeth
'maybe canines' is the definition.
(canine is a type of tooth)
'part of golf course on thursday' is the wordplay.
'part of golf course' becomes 'tee' ('tee' is part of 'golf course').
'on' says to put letters next to each other.
'thursday' becomes 'th' (common abbreviation).
'tee'+'th'='TEETH'
'in' acts as a link.
(Other definitions for teeth that I've seen before include "Structures in the jaws" , "Canines, molars, etc" , "symbols of legal power?" , "Choppers" , "Molars, incisors, etc" .)
