Account given by setter reaches pinnacle (4)
I believe the answer is:
acme
'pinnacle' is the definition.
(synonyms)
'account given by setter' is the wordplay.
'account given' becomes 'ac' (I am not sure about the 'given' bit.).
'by' says to put letters next to each other.
'setter' becomes 'me' (the setter of the clue).
'ac'+'me'='ACME'
'reaches' acts as a link.
Can you help me to learn more?
(Other definitions for acme that I've seen before include "Pinnacle" , "Peak of perfection" , "Highest point (of something)" , "Top or highest point" , "'Highest point, apex (4)'" .)
