Major (adjective) — more important, more serious, or greater in scale than other things of the same kind: a major problem, a major road, a major achievement.
Major (noun) — (1) a student's main subject of study at university: Her major is French; (2) a military officer rank above captain: He was promoted to major.
Major (verb) — to specialise in a subject as your main area of study at university: She majored in economics.
What Does Major Mean?
Major comes from the Latin major, the comparative form of magnus meaning "great" or "large". It entered English in the 16th century via Old French and has remained a high-frequency word ever since. The same Latin root gives us majority, majesty, majestic, and the suffix -or in words like senator and emperor.
As an adjective, major is the most versatile of the three uses. It appears before nouns to indicate that something is more important, more serious, or larger in scale than comparable things: a major breakthrough, a major concern, a major city. In academic writing, it is a precise and respected word. In everyday speech, it can also express genuine surprise or emphasis: "That was a major mistake!"
In British English, the noun sense meaning a university subject (her major is biology) is relatively uncommon — you would more typically say she is studying biology or her degree is in biology. The verb to major in is also more characteristic of North American English, though British speakers understand it perfectly well. The military rank sense, however, is fully standard in British English.
In music, a major key uses the larger (major) intervals between notes, giving it a characteristically bright or uplifting sound — in contrast to a minor key, which uses smaller intervals and often sounds darker or more melancholic.

Usage Notes
- Adjective placement: Major almost always appears before the noun it modifies (attributive position). It is rarely used after a linking verb: say it is a major problem, not the problem is major — the second sounds unnatural in most contexts.
- No comparative form: Because major is itself a comparative (from Latin), you do not say more major. Use more significant, more serious, or more substantial instead.
- Register: Major is neutral and suitable for academic essays, news writing, and everyday conversation alike. In very formal prose, principal or primary may be preferred; in informal speech, big or huge are common alternatives.
- Music: When referring to musical keys, major is not interchangeable with minor. C major and C minor are completely different keys with different emotional qualities.
- British vs. American English: The verb use (to major in) and the noun sense (university subject) are common in American English but less so in British English, where speakers prefer to study and degree subject.

Etymology
From Latin major, comparative of magnus ("great, large"). Entered Middle English in the 16th century via Old French majeur. Related words in English include majority (15th c.), majesty (14th c., via Old French majeste), and major-domo (17th c., from Medieval Latin major domus, "chief of the house"). The musical sense of "major key" (as opposed to "minor key") derives directly from the Latin meaning "greater", referring to the wider intervals in a major scale.
