Start to ignite? (3,3)
I believe the answer is:
set off
This might be a double definition.
'start' is the first definition.
(synonyms)
'ignite?' is the second definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'to' is the link.
Can you help me to learn more?
(Other definitions for set off that I've seen before include "'Leave on a journey (3,3)'" , "Commence journey or explode bomb" , "Depart" , "Begin journey or detonate bomb" , "Start journey or detonate bomb" .)
