Soldier to hear plain order for equipment (13)
I believe the answer is:
paraphernalia
'equipment' is the definition.
(I know that paraphernalia is a type of equipment)
'soldier to hear plain order' is the wordplay.
'soldier' becomes 'para' (short for paratrouper).
'to' means one lot of letters go next to another.
'order' is an anagram indicator.
'hear'+'plain'='hearplain'
'hearplain' anagrammed gives 'phernalia'.
'para'+'phernalia'='PARAPHERNALIA'
'for' acts as a link.
(Other definitions for paraphernalia that I've seen before include "Odds and ends needed for a particular pursuit" , "Sundry equipment" , "Kit needed for a task" , "Miscellaneous stuff" , "Objects and accessories" .)
