From the first we are faster (7)
I believe the answer is:
swifter
'are faster' is the definition.
('swift' can be similar in meaning to 'fast')
'from the first we' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'first'+'we'='firstwe'
'firstwe' anagrammed gives 'SWIFTER'.
(Other definitions for swifter that I've seen before include "Quicker" , "More quickly moving" , "More rapid" , "relatively fast" .)
