Modernist novel which introduces a certain Bloom (7)
I believe the answer is:
orlando
I believe this clue is a double definition.
'modernist novel' is the first definition.
(Virginia Woolf novel)
'which introduces a certain bloom' is the second definition.
(actor Orlando Bloom)
(Other definitions for orlando that I've seen before include "US city" , "American themepark location" , "Florida city; V. Woolf book" , "Shakespeare hero - book by Virginia Woolf" , "southeastern city" .)
