Crossword Genius

Uncle Arthur not entirely lucid (5)

Ross

I believe the answer is:

clear

'lucid' is the definition.
('clear' can be similar in meaning to 'lucid')

'uncle arthur not entirely' is the wordplay.
'not entirely' indicates a hidden word.
'CLEAR' is hidden in the letters of 'uncle arthur'.

(Other definitions for clear that I've seen before include "Easily understood" , "Transparent or cloudless" , "Obvious; jump over" , "Bright" , "Understandable" .)

I've seen this clue in The Times.
