Morphology
take + leave + of + one's + sense
The phrase literally composes 'take' + 'leave' (depart) + 'one's senses' (judgment), so the idea of one's senses 'departing' is metaphorically accessible and parallels common 'lose one's senses' constructions in other languages. However, the formal phrasing 'take leave of' is less frequent and somewhat archaic, so a B1 learner who knows the words may only partially infer the idiomatic sense without prior exposure.
Etymology
The idiom take leave of one's senses comes from the image of your senses taking leave and walking away, like someone leaving the room so your reason is gone. That's why it means 'to act without reason' or 'to behave foolishly'.
