Always wrong about an American patriot (6)
I believe the answer is:
revere
'an american patriot' is the definition.
(Paul Revere, patriot and US founding father)
'always wrong about' is the wordplay.
I cannot really see how this works, but
'always' could be 'ever' (synonyms) and 'ever' is located in the answer.
'about' could be 're' (regarding) and 're' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for revere that I've seen before include "Think a lot of" , "Idolise, venerate" , "Look up to - American patriot, d. 1818" , "Respect, admire deeply" , "Worship and adore" .)
