Formed from them, I pass a liner (9)
I believe the answer is:
steamship
'a liner' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'formed from them i pass' is the wordplay.
'formed from' is an anagram indicator.
'them'+'i'+'pass'='themipass'
'themipass' is an anagram of 'STEAMSHIP'.
Can you help me to learn more?
(Other definitions for steamship that I've seen before include "Tramp, say" , "Queen Elizabeth, for one?" , "What SS stands for" , "Vessel with funnels" , "I pass them (anag) - vessel" .)
