Unattached to small record (6)
I believe the answer is:
single
This clue could be a double definition.
'unattached' is the first definition.
(without a partner)
'small record' is the second definition.
'single' can be an answer for 'record' (I've seen this before). I am not sure about the 'small' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for single that I've seen before include "One-way ticket" , "Unique" , "Like bachelor" , "Sort of person" , "Not married, just the one" .)
