Very pleasant composer welcoming one into company (9)
I believe the answer is:
delicious
'very pleasant' is the definition.
'delicious' can be an answer for 'pleasant' (thesaurus). I am not sure about the 'very' bit.
'composer welcoming one into company' is the wordplay.
'composer' becomes 'delius' (I've seen this before).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'one' becomes 'i' (Roman numeral).
'into' means one lot of letters goes inside another.
'company' becomes 'co' (abbreviation).
'i' put inside 'co' is 'cio'.
'delius' enclosing 'cio' is 'DELICIOUS'.
Can you help me to learn more?
(Other definitions for delicious that I've seen before include "See 3" , "Pleasant tasting" , "Scrumptious" , "very nice" , "Delightful; tasty" .)
