Aimless type all at sea? (7)
I believe the answer is:
drifter
'sea?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'aimless type all' is the wordplay.
'aimless' becomes 'drift' (I've seen this before).
'type all' becomes 'er' (I can't justify this - if you can you should believe this answer much more).
'drift'+'er'='DRIFTER'
'at' is the link.
Can you help me to learn more?
(Other definitions for drifter that I've seen before include "Fishing boat; hobo" , "tramp, perhaps" , "Fishing boat; nomad" , "Vagabond" , "One who moves about aimlessly" .)
