Group of golfers wearing small jumpers possibly getting temporary replacements (8)
I believe the answer is:
stopgaps
'getting temporary replacements' is the definition.
I can't judge whether this definition defines the answer.
'group of golfers wearing small jumpers' is the wordplay.
'group of golfers' becomes 'pga' (I can't explain this - if you can you should believe this answer much more).
'wearing' is an insertion indicator.
'small' becomes 's' (abbreviation - e.g. clothes size).
'jumpers' becomes 'tops'.
's'+'tops'='stops'
'pga' going within 'stops' is 'STOPGAPS'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for stopgaps that I've seen before include "Temporary expedients, for closing holes?" , "Temporary substitutes, like fingers in dykes" , "Temporary measures" , "Temporary or emergency substitutes" , "Temporary substitutes or expedients" .)
