Acostar means ‘to put to bed, to lay down’ and acostarse means ‘to go to bed, to lie down’. Acostarse is the reflexive form of acostar, so it always takes a reflexive pronoun – me, te, se, nos, os or se – that matches the subject. The verb itself is conjugated the same way: in the present tense, yo acuesto becomes me acuesto. In the affirmative tú imperative the pronoun attaches to the end of the verb, so acuesta becomes acuéstate.

Great program that has and is helping me immensely. Four years [studying Spanish] and after just a couple of days with this app I finally am 'getting' the verb thing into my head. After the first couple of lessons I finally feel comfortable conversing with the natives here in Panama. I still have a long way to go but this application was the key for me. Thank you!
