What it means
حساسیت (hassâsiyat) comes from the Arabic root ح-س-س (h-s-s), meaning to feel or perceive. The Arabic suffix “-iyyat” forms abstract nouns, so حساسیت literally means “the quality of being sensitive.” In medical contexts it means allergy or hypersensitivity, used side by side with the French loanword آلرژی (âlerzhi). In everyday speech حساسیت is often preferred because it also covers emotional and psychological sensitivity, such as being sensitive about a topic or delicate in temperament. A close contrast: آلرژی is almost always strictly medical, while حساسیت stretches into personality and emotion as well.
How to use it
- به گرده حساسیت دارم. (be garde hassâsiyat dâram.) “I am allergic to pollen.”
- پوستش خیلی حساسیت داره. (pust-ash kheyli hassâsiyat dâre.) “His skin is very sensitive.”
- این حساسیتِ تو رو نمیفهمم. (in hassâsiyat-e to ro nemi-fahm-am.) “I don’t understand this sensitivity of yours.”
- دکتر گفت حساسیت به لاکتوز داری. (doktor goft hassâsiyat be lâktoz dâri.) “The doctor said you have lactose sensitivity.”
Cultural note
Because حساسیت bridges the physical and emotional meanings of “sensitivity,” it appears frequently in everyday Persian conversation well beyond medical settings. Saying someone حساسیتِ زیادی داره (hassâsiyat-e ziâdi dâre, has a lot of sensitivity) can refer to allergies, thin skin in a social sense, or a refined artistic temperament depending on context. This dual register makes it one of the more versatile Arabic loanwords in modern Persian, fully absorbed and treated as a native word by most speakers.
