hereinkommen

Neutral but a bit more formal/literary: “to enter” or “to step in.” It sounds slightly more formal than plain colloquial entry.

Colloquial and very common: “to come in” or “to get inside.” Very close to the primary meaning.

Means “to come/enter inside,” with emphasis on movement from outside to inside. Slightly more neutral/bookish than “reinkommen.”

Usually means “to arrive” or “to reach a place,” not just “to enter.” For this meaning, it fits only in the sense of arriving somewhere.

Means “to break in” illegally. It is not normal “to enter,” but a negative act of forced entry.

Literally “to go inside.” It emphasizes the act of moving into a place.

A bookish and uncommon construction that often sounds unnatural in everyday speech. Usually it is better to say “eintreten” or “hineingehen.”

In the sense of “to let in” or “admit,” it means not just entering yourself, but being allowed in by someone. Often used with people rather than simple movement.
