Figure there’s a strangely tinny effect about a note (6)
I believe the answer is:
ninety
'figure' is the definition.
(I've seen this before)
'tinny effect about a note' is the wordplay.
'effect' indicates anagramming the letters (I've seen 'effects' mean this).
'about' is an insertion indicator.
'a note' becomes 'e' (musical note).
'tinny' anagrammed gives 'ninty'.
'ninty' placed around 'e' is 'NINETY'.
'there's a strangely' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ninety that I've seen before include "Minutes played in a football match" , "XC in Roman numerals" , "quite an age" , "Minutes in a soccer game" , "Quantity" .)
