Anti-tank giant? (5)
I believe the answer is:
titan
'giant?' is the definition.
(titans are giant mythological creatures)
'anti-tank' is the wordplay.
'TITAN' is hidden within the letters.
However, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for titan that I've seen before include "one of great importance" , "enormous thing" , "One of elder gods defeated by Zeus" , "Gigantic Greek god" , "Atlas, say" .)
