Scheduled final one delayed (7)
I believe the answer is:
dallied
This could be a double definition.
'scheduled final one' is the first definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'delayed' is the second definition.
Although both the answer and definition are past participle verbs, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for dallied that I've seen before include "moved slowly" , "Idled, loitered" , "Dialled up, having delayed" , "Hung about" , "Dawdled or wasted time" .)
