Definition
Meaning
A first cousin related through two siblings of the same sex (e.g., one's father's brother's child or mother's sister's child).
In kinship terminology, a parallel cousin; a cousin whose parents are same-sex siblings. This contrasts with cross-cousins (children of opposite-sex siblings). The term is used mainly in anthropological and technical genealogical contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- There is no direct one-word equivalent in Russian. The concept would be explained as 'двоюродный брат/сестра по однополым родственникам' or 'параллельный кузен'. Avoid translating 'ortho-' literally as 'ортодоксальный'.
Common Mistakes
- Using it in everyday conversation.
- Confusing it with 'cross-cousin'.
- Spelling as 'orthocousin' without the hyphen.

FAQ
Frequently Asked Questions
No, it is a highly technical term used primarily in anthropology and genealogy. In everyday English, people simply say 'cousin' or describe the specific relationship.
The opposite is a 'cross-cousin', which is the child of one's mother's brother or father's sister (siblings of the opposite sex).
Only if you are writing for a technical audience familiar with kinship terminology. For general audiences, it is better to explain the relationship in plain language.
The hyphen is used because it is a compound noun formed from the Greek prefix 'ortho-' (meaning 'straight' or 'correct') and the English word 'cousin'. The hyphen clarifies it is a single, specific concept.
