: I was wondering about the origin of the phrase "You can count on it".
It is a French Idiom and Figurative Phrase
Vous pouvez y compter 'You can count on it'.
Common in the early to mid 1700's but only in French, British American usage early 1800's often in literature, and then often a French novel.
To locate origin will require French language skill.
