Flexible transport group turns up to host final (7)
I believe the answer is:
elastic
'flexible' is the definition.
(I know that flexible can be written as elastic)
'transport group turns up to host final' is the wordplay.
'transport group' becomes 'cie' (I can't explain this - if you can you should give a lot more credence to this answer).
'turns up' shows that the letters should be reversed in order.
'to host' indicates putting letters inside (inserted letters are hosted or welcomed).
'final' becomes 'last' (synonyms).
'cie' reversed gives 'eic'.
'eic' enclosing 'last' is 'ELASTIC'.
Can you help me to learn more?
(Other definitions for elastic that I've seen before include "Narrow band of rubber" , "Narrow strip of rubber" , "Resilient" , "Flexible, adaptable" , "Pliable" .)
