Masculine describes qualities, characteristics, or styles traditionally associated with men and boys. A deep voice, broad shoulders, and facial hair are masculine physical traits. Certain behaviors and interests, like playing football or working in construction, have historically been considered masculine in many cultures.

You'll hear it in grammar classes too: in languages like Spanish and French, nouns are classified as masculine or feminine. El libro (the book) is masculine in Spanish, while la mesa (the table) is feminine, though this has nothing to do with the actual objects.

What counts as masculine varies widely across cultures and time periods. Ancient Spartan warriors thought long hair was masculine; today's soldiers keep their hair short. In some cultures, showing emotion openly is considered masculine strength; in others, staying calm and private about emotions is seen as more masculine. This shows that masculinity is culturally defined and can vary over time and place.
