The spelling of "kid sister" can be tricky, as it is not always clear whether to use "kid" or "kidd." The correct spelling, however, is "kid sister," with the short "i" vowel sound in "kid." In IPA phonetic transcription, this is represented as /kɪd/ sister. The use of "kid" in this context comes from the slang term for child or young person, and "sister" refers to a female sibling. So, a "kid sister" is a younger sister, often used affectionately as a term of endearment.
Kid sister is a colloquial term used to refer to a younger sister. It is typically used to express a close, protective, and sometimes affectionate relationship between an older sibling, usually a brother, and his younger sister. The term "kid sister" emphasizes the age difference between the siblings and suggests a sense of responsibility or caretaking that the older sibling feels towards the younger sibling. This term is often used to portray the younger sister as someone who is naive, innocent, and in need of guidance and protection.
The term "kid sister" can also connote a sense of camaraderie and playfulness between the siblings. It suggests that they share a bond that goes beyond familial ties, evoking a sense of shared experiences and memories. Additionally, it can be used to express a sense of familiarity and ease when referring to the younger sister.
While the term "kid sister" typically refers to a younger sister, it can also be used metaphorically to describe someone who is younger, more innocent, or less experienced in a particular situation, regardless of gender. In this context, it denotes a sense of protectiveness or a role of guidance by the person using the term.
The word "kid sister" is formed by combining two words: "kid" and "sister".
The term "kid" originally referred to a young goat in Old Norse and Old English, with the sense of something small, young, and playful. Over time, it started to be used more generally to describe a young or juvenile animal or person.
On the other hand, "sister" comes from the Old English word "suster", which can be traced back to the Proto-Germanic word "*swestēr". This has cognates in other Germanic languages, such as German "Schwester" and Dutch "zuster".
So, when combined, "kid sister" is a colloquial way of referring to a younger sister, drawing upon the playful and youthful connotations of the word "kid".
