Worker's wonderfully tipsy time (6)
I believe the answer is:
typist
'worker's' is the definition.
(typist is a kind of worker)
'wonderfully tipsy time' is the wordplay.
I cannot really see how this works, but
an anagram of 'tipsy' is 'typis' which is within the answer.
'time' could be 't' (abbreviation) and 't' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for typist that I've seen before include "One using keyboard" , "Forerunner of the word processor operator" , "Operator of a machine that prints one character at a time" , "Key worker" , "Old secretary" .)
