Male company transported by every carriage (10)
I believe the answer is:
stagecoach
'carriage' is the definition.
(stagecoach is a kind of carriage)
'male company transported by every' is the wordplay.
'male' becomes 'stag' (a stag is a male deer).
'company' becomes 'co' (abbreviation).
'transported by' means one lot of letters goes inside another (some letters carried or transported by others).
'every' becomes 'each' (synonyms).
'co' put inside 'each' is 'ecoach'.
'stag'+'ecoach'='STAGECOACH'
(Other definitions for stagecoach that I've seen before include "early form of transport" , "John Wayne film; passenger vehicle" , "Railway company" , "Travelling" , "Great Western" .)
