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' indicates putting letters inside.
'a note' becomes 'e' (musical note).
'tinny' is an anagram of 'ninty'.
'ninty' placed around 'e' is 'NINETY'.
'there's a strangely' 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 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" .)
