Student's room (3)

Ross

I believe the answer is:

den

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

'room' is the definition.
(I know that den is a type of room)

'student's' is the wordplay.
'DEN' is hidden in amongst the letters.
However, I am uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for den that I've seen before include "Room for work or play" , "Animal's lair or gent's study" , "Hideaway" , "Miserable place" , "Animal shelter" .)

I've seen this clue in the Evening Standard.
