Point queen and you, say, at country horse (5)
I believe the answer is:
equus
'horse' is the definition.
(I've seen this before)
'point queen and you say at country' is the wordplay.
'point' becomes 'E' (compass point).
'queen' becomes 'qu' (abbreviation for queen).
'and' says to put letters next to each other.
'you say' becomes 'u' ('you' as it sounds).
'at country' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'e'+'qu'+'u'+'s'='EQUUS'
Can you help me to learn more?
(Other definitions for equus that I've seen before include "Play + Film" , "Drama" , "Peter Shaffer play involving horses" , "Horse genus (Latin)" .)
