Move back to accommodate old novelist (5)

I believe the answer is:

woolf

I'm a little stuck... Click here to teach me more about this clue!

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

I cannot understand how the rest of the clue works.

(Other definitions for woolf that I've seen before include "Virginia -, Eng. writer" , "Author of To the Lighthouse" , "Novelist" , "Political writer" , "Virginia - - wrote 'Orlando'" .)

I've seen this clue in The Times.
