Intended having excellent time (5)
I believe the answer is:
meant
'intended' is the definition.
(to mean something is to intend it)
'excellent time' is the wordplay.
'excellent' becomes 'mean' (I am not sure about this - if you are sure you should believe this answer much more).
'time' becomes 't' (abbreviation).
'mean'+'t'='MEANT'
'having' is the link.
Can you help me to learn more?
(Other definitions for meant that I've seen before include "Deliberate" , "Aimed" , "planned" , "Intended, had in mind" , "Had as intention or purpose" .)
