Indonesian Pronoun "In": The Second-Person Singular

In Indonesian (Bahasa Indonesia), "in" is not a standard pronoun. The correct second-person singular pronouns are:

• Kamu — Informal, familiar (friends, peers, younger people)
• Anda — Formal, polite (strangers, elders, professional, written)
• Kalian — Plural "you all" (informal)
• Anda sekalian / Bapak/Ibu sekalian — Plural formal

"In" may appear in:

• Dialects/Regional varieties: Some local languages (e.g., Javanese, Sundanese, Batak) have distinct pronouns; code-switching occurs.
• Typo/OCR error: For "ini" (this/that), "kamu" (misread), or "Anda" (misread).
• Slang/Internet shorthand: Rare, non-standard.

Standard Indonesian uses kamu (informal) and Anda (formal) for singular "you." "In" is not a recognized form in the official language (KBBI).
