Upturn in good crafty things – leg breaks – follow on? (8)
I believe the answer is:
straggle
'follow on?' is the definition.
(to straggle is to follow behind)
'upturn in good crafty things leg breaks' is the wordplay.
'upturn in' says the letters should be written in reverse.
'good' becomes 'g' (abbreviation).
'crafty things' becomes 'arts' (as in arts and crafts).
'breaks' is an anagram indicator.
'g'+'arts'='garts'
'garts' back-to-front is 'strag'.
'leg' anagrammed gives 'gle'.
'strag'+'gle'='STRAGGLE'
(Other definitions for straggle that I've seen before include "Lag behind" , "String out" , "Spread out irregularly" , "Untidy group" , "Linger behind" .)
