Whether you’re sending her one of these quotes as a sweet gift or adding a heartfelt caption to an Instagram photo, there’s no better way to tell your sister how much she means to you than with these meaningful words of wisdom.

What Is the Meaning of Sister?

A sister is a female sibling, usually a child’s older or younger sister. The male equivalent is a brother. Sister can also refer to a woman who acts like a sister in her relationship with another person, such as a sorority sister or an aunt’s daughter.

The word sister comes from the Middle English suster, partly from Old Norse systir, and from Old English swustor, sweoster, and swester (“sister, nun”), which are all from Proto-Indo-European *swestr, with cognates in many languages, including West Frisian suster, Dutch zuster, German Schwester, Lithuanian sestra, Russian soror, Albanian vajze, and Sanskrit svsR. It can also refer to a sisterhood of women who live and work together in a religious community.

If an individual has two sisters, she is a twin. A woman who has one sister and is the spouse of a brother is called a sister-in-law. A man’s mother’s sister is his aunt. Sister can also refer to an object, such as a ship or plane. For example, Voyager 2 has a sister ship, Voyager 1, and the Boeing 747 has a sister airliner, the Airbus A319, which is very similar in appearance.

Lastly, sister can also refer to a type of clothing, such as a sweater or pair of pants. It can even refer to an entire collection of clothing, such as a “sister set” or a matching dress and skirt.

There is no other person in the world who knows you as well as your sister. Despite any squabbles or arguments you’ve had over the years, she’s there for you through thick and thin. Whether you’re celebrating her birthday, thinking of ways to surprise her, or just want to let her know how much she means to you, there’s no better way to do so than with one of these meaningful sister quotes.
