First male soldier is stubborn (7)

Ross

I believe the answer is:

adamant

'stubborn' is the definition.
(thesaurus)

'first male soldier' is the wordplay.
'first male' becomes 'adam'.
'soldier' becomes 'ant' (soldier is a type of ant).
'adam'+'ant'='ADAMANT'

'is' acts as a link.

(Other definitions for adamant that I've seen before include "Refusing to budge" , "Impervious to pleas or persuasion" , "Refusing to change one's mind" , "With mind made up" , "Hard stone" .)

I've seen this clue in The Hindu.
