Quick answer
me encanta · me duele · me falta
A whole family of verbs turns the English subject into an indirect object. The thing does the acting, not the person.
The family
| Verb | Literal sense |
|---|---|
| encantar | to delight — I love it |
| interesar | to interest |
| importar | to matter |
| doler | to hurt |
| faltar | to be lacking |
| quedar | to remain |
| parecer | to seem |
| molestar | to bother |
The verb agrees with the thing
The pronoun names the person; the verb agrees with whatever is doing the delighting or hurting.
With a following infinitive the verb stays singular, even with several infinitives: Me encanta leer y viajar.
Emphasis and contrast
Add a mí, a ti, a Juan in front to stress or clarify who. The pronoun still stays.
Memory trick
Turn the English sentence around before you translate: not "I love films" but "films delight me". Then the pronoun and the agreement fall into place.
Typical mistakes
Yo encanto el chocolate.
Me encanta el chocolate.
That says you are enchanting. The person is an indirect object, not the subject.
Me duele mis pies.
Me duelen los pies.
The feet are the subject, so the verb is plural — and body parts take the article, not a possessive.
Me encanta mucho.
Me encanta.
Encantar is already at full strength. Mucho belongs with gustar: me gusta mucho.
