Articulate visionary author raised work awareness (4-6)

I believe the answer is:

well-spoken

'articulate' is the definition.
(I've seen this before)

'visionary author raised work awareness' is the wordplay.
'visionary author' becomes 'Wells' (sci-fi author HG Wells).
'raised' is a reversal indicator (going up in a down clue).
'work' becomes 'op' (abbreviation for opus).
'awareness' becomes 'ken' ('that's out of my ken').
'op' back-to-front is 'po'.
'wells'+'po'+'ken'='WELL-SPOKEN'

(Another definition for well-spoken that I've seen is " Articulate".)

I've seen this clue in The Times.
