Meaning
To be extremely intelligent.
Cultural Background
Intelligence is often associated with 'sharpness' (keskinlik) and 'speed' (hız). Being 'zehir gibi' is the highest form of this praise. Teachers often use this phrase to encourage students who show flashes of brilliance, even if they aren't the most disciplined. In trade (ticaret), being 'zehir gibi' implies not just intelligence but also being savvy and hard to cheat. The use of 'zehir' to mean 'potent' likely stems from the high value placed on concentrated essences in Ottoman medicine and culinary arts.
Use with 'Çalışmak'
To sound most natural, say 'Kafası zehir gibi çalışıyor' instead of just 'Kafası zehir gibi'.
Don't say 'Zehirli'
Remember, 'zehirli' is for snakes and mushrooms. 'Zehir gibi' is for geniuses.
