Small company having 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 don't understand how one could define the other.
'small company having unusually short' is the wordplay.
'small company' becomes 'co' (abbreviation; 'small' indicates a short form).
'having' is a charade indicator (letters next to each other).
'unusually' indicates anagramming the letters.
'short' anagrammed gives 'horts'.
'co'+'horts'='COHORTS'
Can you help me to learn more?
(Other definitions for cohorts that I've seen before include "Partners" , "Henchmen" .)
