Flight showing off space age at the foundation (6)
I believe the answer is:
escape
'flight' is the definition.
(flight can mean an escape)
'off space age at the foundation' is the wordplay.
'off space age' becomes 'scape' (I can't explain this - if you can you should give a lot more credence to this answer).
'at' says to put letters next to each other (I've seen this in other clues).
'foundation' suggests the final letters (the letter at the bottom of the word).
The final letter of 'the' is 'e'.
'scape' put after 'e' is 'ESCAPE'.
'showing' is the link.
Can you help me to learn more?
(Other definitions for escape that I've seen before include "Outlet" , "Elude; leakage" , "Get free from confinement or control" , "Do a runner" , "Get away from captivity" .)
