Definition

Noun: 1. An informal or affectionate term for a sister: "Sis" is a casual, often affectionate, abbreviation for "sister," referring to a female sibling. 2. (As a form of address): Used to directly address one's sister or, informally, a close female friend.

Usage

"Sis" is primarily used in informal, spoken contexts. It conveys familiarity, affection, or camaraderie. It is less formal than "sister."

Examples

  • As a form of address: "Hey, sis, can you help me with this?"
  • In informal writing: "Texted my sis about the plans."
Advanced Usage

    • "You look amazing, sis!" (Said to a friend.)
  • The phrase "sis boom bah" is an exclamation of enthusiasm, often associated with cheerleading, and is unrelated to the familial meaning of "sis."
Variants and Related Words

Notes on Meaning
