Reversible brim for Royal Ascot, say? (4)
I believe the answer is:
meet
'royal ascot say?' is the definition.
The answer and definition can be both to do with fundamental existence as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'reversible brim' is the wordplay.
'reversible' is a reversal indicator.
'brim' becomes 'teem' (I've seen this in another clue).
'teem' reversed gives 'MEET'.
'for' is the link.
Can you help me to learn more?
(Other definitions for meet that I've seen before include "Countryside assembly now perhaps not legal" , "club" , "It is proper to encounter" , "See 24" , "Fitting - encounter" .)
