"sentir"pronounce -cen teer or sien teer It is actually "sentirse" which is reflexive literally meaning it reflects back to the person it refers to Como te sientes? How do you feel? The reflexive pronoun te is very important because it reflects back to the person who actually "feels." You cant just say Como sientes? Grammatically it makes no sense. If you want to say I feel "me siento" is more grammatically correct.
