I believe the answer is:

hostel

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

'in changing accommodation he lost' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'accommodation he lost' is the wordplay.
'accommodation' indicates anagramming the letters.
'he'+'lost'='helost'
'helost' with letters rearranged gives 'HOSTEL'.

Can you help me to learn more?

(Other definitions for hostel that I've seen before include "Cheap accommodation for hikers" , "B & B" , "Cheap lodgings" , "Cheap lodging-house for young travellers" , "Lodging-house for students, backpackers, etc." .)
