[MUSIC] There's another group of verbs that uses reflexive pronouns to express the idea of becoming or getting. This new resulting state can then be captured with the expression estar plus a past participle of the same verb. The past participles end in -ado for -ar verbs, and -ido for -er/-ir verbs. And it always agrees with the subject. You can also use ponerse, plus an adjective to express the idea of becoming, especially with mental states. Ponerse triste, To get sad. Ponerse nervioso, To get nervous. Ponerse alegre, To become happy. Ponerse molesto, To become upset or bothered. Ponerse enfermo, To fall sick. There are some more verbs in this group.

Aburrirse, To become bored. Estar aburrido, To be bored. Enamorarse, To fall in love. Estar enamorado, To be in love. Engordarse, To become fat. Estar gordo, To be fat because you've just been doing a lot of eating. Here are some more examples. Me canso del frío en enero, I really get tired of cold weather in January. Estoy cansado del frío, I'm tired of this cold weather. ¿Te deprimes con el frío?, Do you get depressed with the cold weather? Sí, estoy deprimido con el frío, Yes, I am depressed with the cold. Ella se enamora de los niños, She falls in love with all children. Estra enamorada de los niños, She's in love with the children. Again, the reflexive pronoun plus the verb signals the process of becoming. And estar plus the past participle describes the resulting state.
