Brief script, yet evenly read (6)
I believe the answer is:
recite
'read' is the definition.
(thesaurus)
'brief script yet evenly' is the wordplay.
'brief' becomes 're' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'evenly' means one should take alternating letters (even-numbered letters only).
'script'+'yet'='scriptyet'
The alternating letters of 'scriptyet' are 'cite'.
're'+'cite'='RECITE'
(Other definitions for recite that I've seen before include "Read out" , "Give detailed account" , "Repeat aloud form memory( 6)" , "Intone" , "deliver lines that have been recalled" .)
