Galloped hard, circling Charlie's farm (5)
I believe the answer is:
ranch
'farm' is the definition.
(I know that ranch is a type of farm)
'galloped hard circling charlie's' is the wordplay.
'galloped' becomes 'ran' (I've seen this in other clues).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'circling' is an insertion indicator (circling can mean going around or containing).
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'ran'+'h'='ranh'
'ranh' going around 'c' is 'RANCH'.
(Other definitions for ranch that I've seen before include "Cattle breeding farm" , "Agricultural business" , "agricultural land" , "North American stock farm" , "Large tract of land for raising livestock" .)
