Mark and I keeping lots of coffee for Italian who worked in bars (9)
I believe the answer is:
scarlatti
'italian who worked in bars' is the definition.
The definition suggests a singular noun which matches the answer.
'mark and i keeping lots of coffee' is the wordplay.
'mark' becomes 'scar' (mark left by an injury).
'and' says to put letters next to each other.
'keeping' indicates putting letters inside (some letters kept inside).
'lots of' means to remove the last letter (most but not all of the letters).
'coffee' becomes 'latte' (type of coffee drink).
'scar'+'i'='scari'
'latte' with its last letter taken off is 'latt'.
'scari' placed around 'latt' is 'SCARLATTI'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for scarlatti that I've seen before include "Cantatas by him?" , "opera producer" , "Italian scoring" , "Italian composer of many keyboard works" , "scorer" .)
