Partly cover lapel? (7)
I believe the answer is:
overlap
I believe this is a double definition.
'partly cover' is the first definition.
(I've seen this before)
'lapel?' is the second definition.
(lapel is a kind of overlap)
(Other definitions for overlap that I've seen before include "Partly cover (another object)" , "Outflank" , "Partially cover" , "Partly cover - a plover (anag)" , "Partly coincide in time, area etc" .)
