Company with money, mostly for snakes (6)
I believe the answer is:
cobras
'snakes' is the definition.
(cobra is a kind of snake)
'company with money mostly' is the wordplay.
'company with' becomes 'co' (abbreviation. I am not sure about the 'with' bit.).
'money' becomes 'brass' (brass can informally mean money).
'mostly' means to remove the last letter (most but not all of the word).
'brass' with its last letter removed is 'bras'.
'co'+'bras'='COBRAS'
'for' is the link.
Can you help me to learn more?
(Other definitions for cobras that I've seen before include "Slippery creatures" , "Hooded snakes" , "Venomous tropical snakes" , "Carobs for the reptiles" , "snakes appear" .)
