Written account with Company initial request in red (6)
I believe the answer is:
record
'written account' is the definition.
'record' can be an answer for 'account' (I've seen this before). I'm unsure of the 'written' bit.
'company initial request in red' is the wordplay.
'company' becomes 'co' (abbreviation).
'initial' says to take the initial letters.
'in' means one lot of letters goes inside another.
The first letter of 'request' is 'r'.
'co'+'r'='cor'
'cor' put into 'red' is 'RECORD'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for record that I've seen before include "Register, chronicle" , "Written account of proceedings" , "Highest achievement" , "It provides evidence" , "Make a single" .)
