verb

sentir

feel

Percibir una emoción, dolor o sensación en el cuerpo o la mente.

The Spanish verb sentir has two primary applications:

To feel (physical or emotional): This refers to experiencing sensations in the body or internal emotional states. For example, feeling happy, sad, pain, or cold.
To regret or be sorry: This is used when expressing sorrow, pity, or an apology regarding a situation. For example, saying "I am sorry" for an inconvenience.
To perceive (sensory): In some contexts, it can mean to notice or perceive something through the senses, such as hearing a noise or noticing someone's presence.

Grammar: sentir is an irregular verb of the third conjugation (-ir). It undergoes a stem change (e to ie) in certain forms of the present tense (e.g., yo siento, tú sientes). It is also a transitive verb, meaning it often takes a direct object, or it can be used as a reflexive verb, sentirse , when describing how one feels about oneself.
Origin: The word comes from the Latin verb sentire, which meant to feel, perceive, or think.
