Verbs in -sya: smeyatsya, boyatsya, kupatsya
The tail -sya is an old sebya — yourself — worn down to two syllables. Sometimes it means exactly that: kupatsya is to bathe yourself, odevatsya is to dress yourself. For example: “Дети смеются, и мама смеётся” — The children are laughing, and mom is laughing too. A rule from the Russian course: worked out on examples, not memorized as a wording.
How it works
The tail -sya is an old sebya — yourself — worn down to two syllables. Sometimes it means exactly that: kupatsya is to bathe yourself, odevatsya is to dress yourself.
Often it is just part of the verb: smeyatsya, boyatsya, ulybatsya — without the tail these verbs do not exist. Ya smeyu and ya smeyus are different things: the first is about permission, the second about laughter.
Boyatsya asks for the of-form: boyus vody, boyus temnoty — you are afraid of something. Their non-sya twins keep the ordinary object form: kupat rebyonka, udivlyat druga.

How the rule settles in your head
A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
