Learn Russian: Я хочу познакомиться.

The -ся ending shows that it is a reflexive verb. In English, reflexive verbs often use pronouns like 'myself' or 'yourself', but in Russian, познакомиться simply translates to the action of 'getting acquainted' or 'meeting each other'.

Why is there a soft sign (ь) in the -ться ending of познакомиться?

The soft sign is used here because the verb is in the infinitive form. When a reflexive verb is in the infinitive (the base dictionary form), it always ends in -ться. If it were conjugated for 'he' or 'she' (like 'he gets acquainted'), the soft sign would disappear, leaving just -тся.

Why is познакомиться in the infinitive form here?

Just like in English (I want 'to get' acquainted), when you have two verbs together and the first expresses a desire, the second verb stays in its base dictionary form. Here, хочу is conjugated to match я (I), so the second verb познакомиться stays in the infinitive.

Is хочу a regular verb?

No, the base verb хотеть (to want) is irregular and very important to memorize at this level. While 'I want' is я хочу, the verb switches conjugation patterns when talking about 'we' or 'they' (for example, 'we want' is мы хотим).
