Paraphrases vignette — proper text is regularly ignored (10)
I believe the answer is:
interprets
'paraphrases' is the definition.
(to paraphrase something is to interpret it)
'vignette proper text is regularly ignored' is the wordplay.
'regularly ignored' means one should take alternating letters (letters removed at regular intervals).
'vignette'+'proper'+'text'+'is'='vignettepropertextis'
The alternating letters of 'vignettepropertextis' are 'INTERPRETS'.
(Other definitions for interprets that I've seen before include "Translates" , "plays" .)
