...a lot of unnecessary drug paraphernalia? (7)
I believe the answer is:
needles
'a lot of unnecessary drug paraphernalia?' is the definition.
I can't tell whether this defines the answer.
'a lot of unnecessary' is the wordplay.
'a lot of' means to remove the last letter (most of the word but not all of it).
'unnecessary' becomes 'needless' (similar in meaning).
'needless' with its final letter taken off is 'NEEDLES'.
Can you help me to learn more?
(Other definitions for needles that I've seen before include "is irritating" , "landmark" , "Christmas tree leaves" , "Sewers; annoys" , "nettles" .)
