Drift aloft like an airship (5)
I believe the answer is:
float
'drift aloft like an airship' is the definition.
'float' can be an answer for 'drift' (synonyms). I am not certain of the 'aloft like an airship' bit.
'drift aloft' is the wordplay.
'drift' is an anagram indicator (I've seen 'drifts' mean this).
'aloft' with letters rearranged gives 'FLOAT'.
Can you help me to learn more?
(Other definitions for float that I've seen before include "Lie on the surface of liquid." , "Lie on surface of water" , "Bob" , "Petty cash - rest on a liquid's surface" , "Be buoyant" .)
