📚 Etymology▼
From the Latin word *sinus*, which meant 'curve,' 'fold,' 'hollow,' 'bosom,' or 'bay/gulf.' This original meaning of 'hollow' or 'curve' explains both the anatomical use (a curved part of the body) and the mathematical use (derived from the curve of a circle).

Frequently Asked Questions
Is 'senos' always masculine, even though it refers to a female body part?
Yes, 'senos' is the plural of the masculine noun 'el seno.' The gender of the noun in Spanish does not always match the biological gender of the person or thing it describes. Always use masculine articles and adjectives (e.g., 'los senos grandes').
What is the difference between 'senos' and 'pechos'?
'Senos' is often preferred in formal, medical, or clinical language. 'Pechos' is more general and can refer to the whole chest area for both men and women, but it is also commonly used to mean 'breasts' in everyday conversation.
