The sociolinguist Max Weinreich captured the situation perfectly: "A language is a dialect with an army and a navy." Linguistically, there is no principled boundary between a language and a dialect — the criteria shift depending on what you measure. Mutual intelligibility is the most intuitive test: two varieties are dialects of the same language if speakers can understand each other. But this fails in multiple directions. Norwegian, Swedish, and Danish are mutually intelligible to a high degree yet are counted as three separate languages (reflecting their distinct national identities). Conversely, Mandarin and Cantonese are both called "Chinese" yet are not mutually intelligible at all. Serbian and Croatian are largely mutually intelligible but treated as separate languages for political reasons following the dissolution of Yugoslavia. Linguists generally use more technical criteria — phonological, lexical, and grammatical distance — but even these yield a continuum, not sharp categories. The practical conclusion is that the language/dialect distinction is primarily social and political: varieties spoken by nations with prestige, standardisation, and institutional support get called "languages"; the others get called "dialects."
