Occupants of flat in a tenement of classical style (8)

I believe the answer is:

latinate

'of classical style' is the definition.
(Latin is a classical langugage)

'occupants of flat in a tenement' is the wordplay.
'occupants of' indicates the answer is hidden within the clue (some letters occupying the clue).
'LATINATE' is hidden within 'flat in a tenement'.

(Another definition for latinate that I've seen is " ancient tongue".)

I've seen this clue in The Guardian.
