Briefly consider getting earring (4)
I believe the answer is:
stud
'earring' is the definition.
(I've seen this before)
'briefly consider' is the wordplay.
'briefly' means to remove the last letter.
'consider' becomes 'study' (synonyms).
'study' with its final letter taken off is 'STUD'.
'getting' is the link.
(Other definitions for stud that I've seen before include "Clothes fastener in horse establishment" , "Style of poker" , "Macho man" , "Knob; fastener; boss" , "Macho - stable - boss" .)
