The place in which we accommodated her (5)
I believe the answer is:
where
'the place' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for where that I've seen before include "enquiry" , "A question of place?" , "a question of location" , "In which position?" , "At which point" .)
