Evident father needs temporary accommodation (6)
I believe the answer is:
patent
'evident' is the definition.
(synonyms)
'father needs temporary accommodation' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'needs' means one lot of letters go next to another.
'temporary accommodation' becomes 'tent' (I've seen this before).
'pa'+'tent'='PATENT'
(Other definitions for patent that I've seen before include "Register (an invention)" , "Like a medicine" , "Obvious - protection for inventors" , "glaring" , "Sole right to exploit an invention" .)
