Aha! Repair plan potentially implies lots of equipment (13)
I believe the answer is:
paraphernalia
'equipment' is the definition.
(I know that paraphernalia is a type of equipment)
'aha repair plan potentially' is the wordplay.
'potentially' indicates anagramming the letters (letters have the potential to spell a new word).
'aha'+'repair'+'plan'='aharepairplan'
'aharepairplan' is an anagram of 'PARAPHERNALIA'.
'implies lots of' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for paraphernalia that I've seen before include "Miscellaneous belongings" , "All the extra gear" , "Miscellaneous accessories" , "Miscellaneous things" , "Equipment etc" .)
