Tinny performance with English digit (6)
I believe the answer is:
ninety
'digit' is the definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'tinny performance with english' is the wordplay.
'performance with' indicates an anagram.
'english' becomes 'e' (abbreviation).
'tinny' mixed up with 'e' can make 'NINETY'.
Can you help me to learn more?
(Other definitions for ninety that I've seen before include "6 x 3 x 5" , "high number" , "old age" , "Four score and ten" , "quite an age" .)
