Use the new walkway before titan (10)
I believe the answer is:
prometheus
'titan' is the definition.
(I know that Prometheus is a titan)
'use the new walkway before' is the wordplay.
'new' indicates anagramming the letters.
'walkway' becomes 'prom' (I can't justify this - if you can you should give a lot more credence to this answer).
'before' says to put letters next to each other.
'use'+'the'='usethe'
'usethe' with letters rearranged gives 'etheus'.
'etheus' put after 'prom' is 'PROMETHEUS'.
Can you help me to learn more?
(Other definitions for prometheus that I've seen before include "I stole fire" , "Fireman" , "Gk. hero, gave men fire" , "Greek god" , "Fire-stealing Titan" .)
