Effective new set is most tidy (7)

Ross

I believe the answer is:

neatest

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

'most tidy' is the definition.
('neat' can be similar in meaning to 'tidy')

'effective new set' is the wordplay.
'effective' becomes 'neat' (I can't explain this - if you can you should give a lot more credence to this answer).
'new' is an anagram indicator.
'set' is an anagram of 'est'.
'neat'+'est'='NEATEST'

'is' is the link.

Can you help me to learn more?

(Other definitions for neatest that I've seen before include "best-looking desk, say?" , "Seat ten (anag)" , "Most tidy" , "Most smart" , "Most orderly" .)
