Have something in common with friend, literally? (7)
I believe the answer is:
overlap
'have something in common' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for overlap that I've seen before include "Extend beyond edge of a thing and partly cover it" , "Partly cover (another object)" , "Partly cover - a plover (anag)" , "Extend on top of" , "Partly coincide in time, length etc" .)
