Mulish soldier follows a female animal with offspring (7)
I believe the answer is:
adamant
'animal with offspring' is the definition.
I can't judge whether this definition defines the answer.
'mulish soldier follows a female' is the wordplay.
'mulish soldier' becomes 'ant' (soldier is a type of ant. I am not sure about the 'mulish' bit.).
'follows' means one lot of letters go next to another.
'female' becomes 'dam' (dam is a kind of female).
'a'+'dam'='adam'
'ant' after 'adam' is 'ADAMANT'.
Can you help me to learn more?
(Other definitions for adamant that I've seen before include "Stubbornly firm" , "Completely determined" , "Data man can be quite unyielding" , "Unyielding, won't change mind" , "Definite and unyielding" .)
