A peculiar thing in the Swedish language is how there is a group of verbs, that don’t look like any other common verbs. This because they end on an -s making them look like a regular verb in the passive voice. Now when learning Swedish this will definitely cause a bunch of mixups. These verbs are in fact regular verbs in the active voice. These could either have a completely active function (e.g. svettas (to sweat), andas (to breathe), luras (to fool)), a reciprocal function, which means that they work as a verb between two parties (e.g. slåss (to fight), kyssas (to kiss), skiljas (to part or to get divorced)) or they can be verbs describing a certain state (e.g. brännas (to burn), kännas (to feel), dagas (to dawn)). Some of these verbs have a non-deponent sibling, which makes these verbs look even more like the passive voice and are more prone to getting mixed up. However, these verbs tend to have a completely different meaning, which makes it important not to mix them up.
Deponent verbs without a sibling

Jag andas in luft.

Åldras (to age)

Actually there is a dated but unrelated verb which means to close. You will only ever come across it in the set phrase "bakom lyckta dörrar" (behind closed doors). Compare Danish lukke.
Deponent verbs with a sibling
There are a bunch of verbs with an "active looking" sibling. Some have the same meaning, where the deponent verb has a somewhat “autonomous” meaning (e.g. brännas (to burn), kännas (to feel)) and the active looking verb has a more active feeling to it (e.g. bränna (to burn something), känna (to feel something)). The following verbs are examples of pairs that have totally different meanings and which are more important to not mix up.
