Suitable apartment in short (3)
I believe the answer is:
apt
This could be a double definition.
'suitable' is the first definition.
(apt means appropriate or fitting)
'apartment in short' is the second definition.
'apt' can be an answer for 'apartment' (abbreviation in property ads for example). I am not certain of the 'in short' bit.
Can you help me to learn more?
(Other definitions for apt that I've seen before include "Fit, suitable" , "flat" , "Appropriate for Pat" , "Fitting - inclined" , "Having a tendency" .)
