Wherein residents can get old at some stage (5)
I believe the answer is:
lodge
'some stage' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'wherein residents can get old' is the wordplay.
I cannot quite see how this works, but
an anagram of 'old' is 'lod' which is located in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'at' is the link.
Can you help me to learn more?
(Other definitions for lodge that I've seen before include "Deposit the house at the estate entrance?" , "Gatehouse; beaver's den" , "Small house at gates of park or estate" , "Provide accommodation for" , "pioneer of radiotelegraphy" .)
