Intended for yours truly with a worker (5)
I believe the answer is:
meant
'intended' is the definition.
(to mean something is to intend it)
'yours truly with a worker' is the wordplay.
'yours truly' becomes 'me' (the person that set this crossword).
'with' says to put letters next to each other.
'a worker' becomes 'ant' (worker is a type of ant).
'me'+'ant'='MEANT'
'for' is the link.
(Other definitions for meant that I've seen before include "Intentional" , "no accident" , "Intended, had in mind" , "represented" , "Aimed" .)
