Sentimento vs. sensazione
While both sentimento and sensazione can be translated as feeling in English, they are not interchangeable. The key difference lies in their origin: sentimento comes from the heart and mind (emotions), while sensazione comes from the body and senses (physical perception and gut instincts).
Sentimento
B1A sentimento is a deep, internal, and often complex emotional state. It relates to the heart and mind and includes feelings like love, joy, sadness, nostalgia, and affection. It's generally more profound and lasting than a sensazione. It can also express a considered opinion or a general belief.

(I feel a deep feeling of gratitude for you.)

Sensazione
A2A sensazione refers to a physical perception experienced through the five senses or a state of the body. It describes things like heat, cold, pain, or dizziness. By extension, it also means a more immediate, gut-level instinct, a hunch, or a fleeting impression about a situation or person.

(I have a strange burning sensation on my skin.)

Summary
In short, use sentimento for complex emotions stemming from the heart or mind (love, sadness, gratitude). Use sensazione for physical perceptions from the body (cold, pain, a tickle) or for gut instincts and immediate hunches (a premonition, a first impression). Think of sentimento as emotion or sentiment and sensazione as sensation or hunch.
