Word in Alabama for transport hub (8)
I believe the answer is:
terminal
'transport hub' is the definition.
(I know that terminal is a type of transport hub)
'word in alabama' is the wordplay.
'word' becomes 'term' (term is a kind of word).
'alabama' becomes 'al' (abbreviation).
'term'+'in'+'al'='TERMINAL'
'for' acts as a link.
(Other definitions for terminal that I've seen before include "Deathly" , "Tramline (anag.)" , "Electric connection" , "Passenger building" , "Final or fatal" .)
