Remains with company after start of critical week? It’s a profitable business (4,3)
I believe the answer is:
cash cow
'a profitable business' is the definition.
(I've seen this before)
'remains with company after start of critical week?' is the wordplay.
'remains with' becomes 'ash' (remains of a fire. I am not sure about the 'with' bit.).
'company' becomes 'co' (abbreviation).
'after' says to put letters next to each other.
'start of' says to take the initial letters.
'week?' becomes 'w' (abbreviation).
The initial letter of 'critical' is 'c'.
'ash'+'co'='ashco'
'ashco' put after 'c' is 'cashco'.
'cashco'+'w'='CASH COW'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for cash cow that I've seen before include "troublefree business?" , "Saw choc (anag.); steady investment" , "Lucrative investment" , "profitable business" , "E.g. business milked for money" .)
