✦Grammar Breakdown

Klar,kommrein.

1

Klar (colloquial affirmation)

"Klar" is an informal way to say "sure" or "of course" and is often used in spoken German.

2

komm (imperative du)

"komm" is the singular informal imperative of the verb "kommen" (to come).

3

rein (adverbial direction)

"rein" is a short form of "herein" and functions as an adverb meaning "inwards"; together with "kommen" it forms the phrase "komm rein" = "come in".

4

Verb‑particle separation

In the imperative the particle "rein" stays after the verb, unlike in the infinitive "hereinkommen".

✕Common Mistakes

  • Klar, kommen rein.

    The verb must be in the singular informal imperative form "komm".

  • Klar, komm herein.

    While "herein" is correct, pairing it with the informal imperative sounds too formal; use "rein" for casual contexts.

  • Klar, komm rein!!!

    Exclamation marks are fine, but learners sometimes over‑punctuate with multiple exclamation points, which can look overly enthusiastic in written German.

↔Alternatives

  • Ja, bitte, komm herein.

    Yes, please, come in.

  • Natürlich, treten Sie bitte ein.

    Of course, please come in.

  • Gern, komm rein.

    Gladly, come in.

Cultural Tip

In German, "rein" is a colloquial shortcut for "herein" and is common in everyday speech. Remember to match the level of formality: "komm rein" (du) for friends, "kommen Sie rein" (Sie) for strangers, customers, or elders. Also, Germans often accompany the invitation with a slight nod or a hand gesture toward the entrance.
