Switch company, having no start or end plan (6)
I believe the answer is:
intend
'plan' is the definition.
(I know this)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for intend that I've seen before include "Aim, plan" , "Have as purpose or resolve" , "Mean; aim" , "Mean - purpose" , "Mean; propose" .)
