affinal
uh-FY-nuhl
/əˈfaɪnəl/
Related by marriage; of or relating to in-laws.
Strictly technical and objective, used in legal and anthropological contexts to distinguish in-laws from blood relatives.
The story behind the word. In ancient Rome, 'affinis' described neighbors whose lands bordered each other. Over time, the Romans metaphorically extended this 'bordering' concept to families joined by marriage, creating 'affinal' to describe the legal borders crossed when two families unite.

Memory hook
Think of 'affinity' or 'fine line'. When you marry, you draw a fine line connecting your family to another. Affinal is for in-laws at the border.
When not to use
Do not use in casual, warm family conversations (e.g., 'Come meet my affinal relative' sounds incredibly cold and robotic).
Fun facts
- In mathematics, an 'affine' transformation preserves collinearity, sharing the same Latin root of bordering or aligning.
