All-rounder oddly only making single (5)
I believe the answer is:
alone
'only making single' is the definition.
'alone' can be an answer for 'single' (I've seen this before). I am not sure about the 'only making' bit.
'all-rounder oddly' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'all'+'rounder'='allrounder'
The alternate letters of 'allrounder' are 'ALONE'.
Can you help me to learn more?
(Other definitions for alone that I've seen before include "Exclusively, by oneself" , "unique" , "Without others being involved" , "Exclusively; solitary" , "Note of charges" .)
