Lütfen kapıda bekleyiniz; doktor gelene kadar biz kayıt yapıp sırayı düzenleyeceğiz.

Turkish has different imperative forms that map to levels of politeness and number:

• bekle: 2nd person singular, informal (to one person you know well).
• bekleyin: 2nd person plural or polite (to more than one person, or politely to one person).
• bekleyiniz: extra-formal/polite; common on signs, announcements, or in institutional contexts like hospitals.

Breakdown: bekle-y-iniz (root bekle- + buffer y + -iniz). In everyday speech, bekleyin is more common; bekleyiniz sounds very formal or “announcement-like.”

Kapıda = “at/by the door.” The suffix -DA is the locative case (“in/on/at”) and obeys vowel and consonant harmony:

• Back vowels (a, ı, o, u) → -da
• Front vowels (e, i, ö, ü) → -de Also, D can surface as t after voiceless consonants (e.g., saatte).

Here, kapı ends in a vowel and has a back vowel ı, so we get kapı-da. If you wanted “in front of the door,” you could say kapının önünde.

• gel-en: the participle “the one who comes”
• gel-en-e: add dative -e
• kadar: “until”

Together: gelene kadar ≈ “until (he/she) comes.” It’s a common pattern: participle + dative + kadar.

Variants:

• doktor gelinceye kadar (using -ince “when” + -ye + kadar) = same meaning, slightly more formal/bookish.
• Contrast with doktor gelmeden önce = “before the doctor comes” (not “until”). Different nuance: “before X happens” vs “up to the time X happens.”

-ıp/-ip/-up/-üp is a converb that links verbs with the same subject, often implying sequence:

• kayıt yapıp sırayı düzenleyeceğiz ≈ “we will do the registration and (then) arrange the queue.”

You could say kayıt yapacağız ve sırayı düzenleyeceğiz, but the -ıp form is tighter and more natural when listing successive actions by the same subject.

They overlap but aren’t always interchangeable.

• kayıt yapmak: “to do/make registration,” very common in service contexts (hospitals, offices).
• kaydetmek: “to record/save/register (data),” also common in tech/admin contexts.

In this sentence, kayıt yapıp is perfectly idiomatic. In some contexts you might hear sizi kaydedeceğiz (“we will register you”). Note the forms:

• kaydetmek → kaydediyorum, kaydedeceğiz (not “kaydeceğiz”).

Turkish inserts y between two vowels to prevent hiatus:

• bekle + iniz → bekleyiniz
• sıra + ı → sırayı
• düzenle + ecek + iz → düzenleyeceğiz

This buffer keeps pronunciation smooth.

Yes. A semicolon neatly links two closely related independent clauses. You could also write:

• Lütfen kapıda bekleyiniz. Doktor gelene kadar biz kayıt yapıp sırayı düzenleyeceğiz.
• Or combine with a comma, though a comma between two full clauses is less formal in Turkish.

Yes; Turkish word order is flexible, especially with adverbial clauses. All of these are fine:

• Doktor gelene kadar lütfen kapıda bekleyiniz.
• Lütfen doktor gelene kadar kapıda bekleyiniz.
• Lütfen kapıda, doktor gelene kadar, bekleyiniz. The main meaning remains; small shifts can change emphasis or flow.

Commonly used alternatives:

• Lütfen kapıda bekleyin. (polite, less formal than -iniz)
• Kapıda bekler misiniz, lütfen? (question form softens it: “Would you wait at the door, please?”)
• Kapıda biraz bekleyebilir misiniz? (“Could you wait a bit at the door?” even softer)

Future (-ecek/-acak) here signals a planned/soon-to-happen action during the waiting period. You could also hear the present progressive for actions already underway:

• Kayıt yapıyoruz ve sırayı düzenliyoruz. (“We’re doing the registration and arranging the queue [now].”) Both are natural depending on whether it’s planned/impending vs currently ongoing.
