Stupid dim expression between presidential elections (7)
I believe the answer is:
midterm
'stupid dim expression between presidential elections' is the definition.
I can't tell whether this definition defines the answer.
'stupid dim expression' is the wordplay.
'stupid' is an anagram indicator (in a stupid order).
'expression' becomes 'term' (both can mean a piece of vocabulary).
'dim' with letters rearranged gives 'mid'.
'mid'+'term'='MIDTERM'
Can you help me to learn more?
(Other definitions for midterm that I've seen before include "period of pregnancy?" , "Halfway through a pregnancy" , "Non-presidential (US elections)" , "In the middle of a period of office" , "Half-way through (time in office)" .)
