Synonym discussion

Sense: adjective/1

Long-time, long-standing, established, and veteran all describe something that has existed or been true for an extended period, but each has a different tone and typical context. Long-time is the most neutral and person-focused: you have a long-time friend, a long-time customer, or a long-time resident. Long-standing leans formal and is better suited for institutions or situations — a long-standing tradition, a long-standing agreement. Established adds a sense of recognition or institutional acceptance — an established practice, an established member of the community. Veteran, slightly informal, emphasises hands-on experience — a veteran teacher, a veteran campaigner. Use long-time when you simply want to say 'for many years' without extra nuance; choose long-standing or established when more formality is needed, and veteran when the person's deep experience is the key point.

Etymology

Old EnglishEnglish

Long-time is a compound formed from the adjective long (Old English lang, 'of great length') and the noun time (Old English tīma, 'a period'). It first appeared in written English in the early 19th century as a hyphenated attributive adjective. The one-word variant longtime (without hyphen) is common in American journalism, while the hyphenated form remains standard in British and more formal writing.
