To conspire together; to plot or plan jointly with others toward a common goal.
From co- (together) + inspire or directly from con- (together) + spirare (to breathe). The prefix suggests working together in secret or with common purpose, like 'breathing together.'
The root of 'conspiracy' comes from Latin 'conspirare' (literally 'to breathe together'), so 'coinspire' is just another way to say people are plotting—all huddled close, speaking in whispers, literally synchronized.
