Half share in a house? (4)
I believe the answer is:
semi
This clue might be a double definition.
'half' is the first definition.
(I've seen this before)
'share in a house?' is the second definition.
'semi' can be an answer for 'house?' (short for semi-detached). I'm not sure about the 'share in a' bit.
Can you help me to learn more?
(Other definitions for semi that I've seen before include "Connected house" , "House joined to another" , "Half (pfx)" , "House attached to one other" , "Type of house (UK) - type of truck (US)" .)
