I'm a little stuck... Click here to teach me more about this clue!

'quite unexceptional' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'each person' is the wordplay.
'each' becomes 'every' (synonyms).
'person' becomes 'one' ('one' can mean an unspecified person).
'every'+'one'='EVERYONE'

'is' is the link.

Can you help me to learn more?

(Other definitions for everyone that I've seen before include "All the people" , "Entire group" , "the masses" , "All without exception" , "Uncle Tom Cobleigh and all" .)

I've seen this clue in the Evening Standard.
