Artist's sudden change of direction, absorbing right tips from Magritte (7)
I believe the answer is:
vermeer
'artist's' is the definition.
(Johannes Vermeer, 1632-1675)
'sudden change of direction absorbing right tips from magritte' is the wordplay.
'sudden change of direction' becomes 'veer' (veer can mean a change of direction).
'absorbing' indicates putting letters inside.
'right' becomes 'r' (abbreviation).
'tips from' says to hollow out the word (remove centre letters).
'magritte' with its middle taken out is 'me'.
'r'+'me'='rme'
'veer' placed around 'rme' is 'VERMEER'.
(Other definitions for vermeer that I've seen before include "Jan -, seventeenth-century Dutch painter" , "Dutch painter, 1673-75" , "'Dutch painter, noted for his use of light (7)'" , "Painter active in Delft, d. 1675" , "Girl with a Pearl Earring artist" .)
