Day worker holds European qualification for starter (8)
I believe the answer is:
debutant
'starter' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'day worker holds european qualification' is the wordplay.
'day' becomes 'd' (abbreviation for day).
'worker' becomes 'ant' (worker is a type of ant).
'holds' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'qualification' becomes 'but' (I can't justify this - if you can you should give a lot more credence to this answer).
'd'+'ant'='dant'
'e'+'but'='ebut'
'dant' placed around 'ebut' is 'DEBUTANT'.
'for' is the link.
Can you help me to learn more?
(Other definitions for debutant that I've seen before include "One making first appearance" , "Newcomer to team" , "Someone making their first appearance" , "Beginner, first-timer" .)
