Муж (everyday) and супруг (formal) - two words for husband, one irregular plural, and a word root that connects husband, man, and courage in a single etymological thread.
Муж has an irregular plural: мужья (not *мужи). This follows the same -ья pattern as брат → братья and друг → друзья.
But the deeper grammar insight is the root муж-, which generates an entire word family:
муж (husband) → мужчина (man) → мужество (courage/manhood) → мужественный (courageous) → мужской (masculine/men's)
Russian word roots work like this - one root radiates outward into nouns, adjectives, and abstract concepts. Recognizing муж- in мужчина or мужество lets you decode words you've never seen before.

"Муж" is casual; "супруг" is for paperwork. In everyday Russian, you always say "мой муж." Using "мой супруг" in conversation sounds stilted - like saying "my spouse" instead of "my husband" in formal English. Супруг appears on marriage certificates, in legal documents, and in news reporting.
"Мой муж" is how you introduce him. The standard introduction is "Это мой муж, [name]" (This is my husband, [name]). Unlike some cultures, Russians don't typically use first names alone when introducing a spouse to strangers - the relationship label comes first.
The word муж once meant "man" generally. In Old Russian, муж meant simply "man" - not specifically "husband." The meaning narrowed over centuries, while мужчина took over the general meaning of "man." This is why мужество (courage) derives from "husband" - it originally derived from "man."
