Just stupid — introduction of corporate tax, supporting peers, essentially (5)
I believe the answer is:
exact
'just' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'stupid introduction of corporate tax supporting peers essentially' is the wordplay.
'stupid' indicates anagramming the letters (in a stupid order).
'introduction of' suggests taking the first letters.
'supporting' means one lot of letters go next to another (in a down clue, some letters go below others).
'essentially' says to take the centre.
The middle of 'peers' is 'e'.
The first letter of 'corporate' is 'c'.
'c'+'tax'='ctax'
'ctax' anagrammed gives 'xact'.
'xact' after 'e' is 'EXACT'.
Can you help me to learn more?
(Other definitions for exact that I've seen before include "Absolutely right" , "Correct; insist on" , "Precise, accurate" , "On the nail" , "correct in every detail" .)
