Small company with unusually short Roman soldiers (7)
I believe the answer is:
cohorts
'roman soldiers' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
'small company with unusually short' is the wordplay.
'small company' becomes 'co' (abbreviation; 'small' suggests an abbreviation).
'with' is a charade indicator (letters next to each other).
'unusually' indicates an anagram.
'short' is an anagram of 'horts'.
'co'+'horts'='COHORTS'
Can you help me to learn more?
(Other definitions for cohorts that I've seen before include "Henchmen" , "Partners" .)
