Notice extremely explicit point of sale? (6)
I believe the answer is:
market
'point of sale?' is the definition.
'market' can be an answer for 'sale?' (thesaurus). I'm unsure of the 'point of' bit.
'notice extremely explicit' is the wordplay.
'notice' becomes 'mark' (synonyms).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'explicit' with its centre removed is 'et'.
'mark'+'et'='MARKET'
Can you help me to learn more?
(Other definitions for market that I've seen before include "World of commercial activity" , "Commercial location" , "Advertise, promote" , "Place where things are bought and sold" , "Trading centre" .)
