Terribly old, nearly all get accommodation (5)
I believe the answer is:
lodge
'accommodation' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'terribly old nearly all get' is the wordplay.
'terribly' indicates an anagram.
'nearly all' means to remove the last letter (most but not all of the word).
'get' with its last letter taken away is 'ge'.
'old' is an anagram of 'lod'.
'lod'+'ge'='LODGE'
Can you help me to learn more?
(Other definitions for lodge that I've seen before include "Fix" , "Masonic meeting place" , "Beaver's home - hunters use it!" , "Stay temporarily, with bed and board" , "pioneer of radiotelegraphy" .)
