Stupid woman got married (3)
I believe the answer is:
dim
'stupid' is the definition.
(similar in meaning)
'woman got married' is the wordplay.
'woman' becomes 'di' (short for Diana).
'got' means one lot of letters go next to another.
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'di'+'m'='DIM'
(Other definitions for dim that I've seen before include "Not bright, cloudy" , "out of mind?" , "Lose brightness" , "Obscure, not bright" , "Unpromising" .)
