Wrap sticker and ring around it (7)
I believe the answer is:
burrito
'wrap' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'sticker and ring around it' is the wordplay.
'sticker' becomes 'burr' (I am not sure about this - if you are sure you should believe this answer much more).
'and' says to put letters next to each other.
'ring' becomes 'o'.
'around' means one lot of letters goes inside another.
'burr'+'o'='burro'
'burro' enclosing 'it' is 'BURRITO'.
Can you help me to learn more?
(Other definitions for burrito that I've seen before include "Tortilla folded around a savoury filling" , "Mexican dish - rub trio (anag)" , "that's eaten in Mexico" , "Mexican dish of tortilla folded around a filling" , "Tortilla folded round a filling" .)
