Quite a different (and touching) expression for summer? (8)
I believe the answer is:
equation
'expression for summer?' is the definition.
I can't tell whether this definition defines the answer.
'quite a different and touching' is the wordplay.
'different' is an anagram indicator.
'and' means one lot of letters go next to another.
'touching' becomes 'on'.
'quite'+'a'='quitea'
'quitea' is an anagram of 'equati'.
'equati'+'on'='EQUATION'
Can you help me to learn more?
(Other definitions for equation that I've seen before include "Mathematical relationship" , "feature of maths" , "Mathematically, two are equal" , "Mathematical statment that two are equal" , "Statement that two things have the same value" .)
