I next catch, through being clumsy (8)
I believe the answer is:
inexpert
'clumsy' is the definition.
(I've seen this before)
'i next catch through' is the wordplay.
'catch' indicates putting letters inside.
'through' becomes 'per' (I've seen this before).
'next' enclosing 'per' is 'nexpert'.
'i'+'nexpert'='INEXPERT'
'being' is the link.
(Other definitions for inexpert that I've seen before include "Green" , "with little skill" , "Offering little professionally" , "not good enough" , "Clumsy" .)
