Intuizione vs. presentimento vs. sensazione
While intuizione, presentimento, and sensazione can all be translated as hunch or gut feeling, they carry distinct nuances in Italian. Intuizione is a sudden insight, presentimento is a premonition of a future event, and sensazione is a more general, vague feeling about a situation.
Intuizione
B2This word refers to a sudden flash of insight or a quick understanding that appears to come from the mind. It is like an intellectual aha! moment that helps solve a problem, understand a complex situation, or make a correct snap judgment. It is more of a cognitive realization than an emotional feeling.
Ho avuto l'intuizione di controllare sotto il letto e ho trovato le chiavi.
(I had the hunch to check under the bed and found the keys.)
La sua fu un'intuizione geniale che cambiò il corso della ricerca.
(His was a stroke of genius that changed the course of the research.)
Seguendo la mia prima intuizione, ho scelto la risposta giusta all'esame.
(Following my first gut feeling, I chose the right answer on the exam.)
L'investigatore ha risolto il caso grazie a una brillante intuizione.
(The detective solved the case thanks to a brilliant insight.)
Presentimento
B2This word describes a premonition or a foreboding about a future event. It is almost always associated with a negative or unsettling feeling that something bad is about to happen. It is an emotional, anxious, and often vague feeling of dread, not an intellectual insight.
Avevo un brutto presentimento riguardo a quel viaggio e infatti abbiamo perso l'aereo.
(I had a bad feeling about that trip, and indeed we missed the plane.)

(Since this morning I've had a vague premonition that something is wrong.)

(When he said goodbye to me, I had a feeling that I would never see him again.)
Ignorò il suo presentimento e accettò l'offerta di lavoro, pentendosene poi.
(He ignored his gut feeling and accepted the job offer, regretting it later.)
Sensazione
B1This is the most general and neutral term of the three. It describes a vague feeling, impression, or hunch about a person or a situation, usually in the present or very near future. It can be positive, negative, or neutral. It is most commonly used in the phrase ho la sensazione che... which means I have a feeling that...
Ho la sensazione che oggi sarà una bella giornata.
(I have a feeling that today will be a beautiful day.)
Quel posto mi dà una strana sensazione, preferirei non entrare.
(That place gives me a strange feeling, I'd rather not go in.)

(I don't know why, but I have a gut feeling we shouldn't trust him.)

(I have a feeling I've forgotten something important at home.)
Summary
In short, use intuizione for a sudden, smart idea or a problem-solving realization. Use presentimento for a dark, emotional premonition about something bad happening in the future. Use sensazione for a general, all-purpose gut feeling or impression about a current situation, which can be positive, negative, or neutral.
