An accent is a way of pronouncing a language. A dialect is broader: it covers pronunciation and also vocabulary and grammar. Everyone who speaks has an accent, and some linguists treat accent differences as part of dialect differences.
Key takeaways
- Accent is about how words sound, while dialect also includes word choice and grammar.
- Linguists such as John Lyons count accent differences as a subset of dialect differences.
- The map shows languages, not accents or dialects, so it cannot tell you how a place sounds.
- Welsh is listed with about 724,000 speakers (Wikidata (unreferenced)) as one language on our map, though its speech varies by region.
How accent and dialect differ
The two words overlap, and they are not always used the same way. In the usual distinction, an accent describes differences in how words are pronounced, while a dialect covers more: differences in grammar and vocabulary too [1]. The Wikipedia article on dialects also quotes the linguist John Lyons, who notes that many linguists place differences of accent under differences of dialect [1]. On that view accent is one part of dialect, not a rival to it.
A quick test is to ask what changes. If someone says the same sentence with different vowels but the same words and grammar, that is an accent difference. If they use a different word for the same thing, or build the sentence differently, that is a dialect difference, and it usually comes with an accent too.
Linguists use "dialect" as a neutral term for a variety of a language, with no suggestion of being lower status. For how Glottolog uses the term, see its glossary [2]. Where one variety ends and the next begins is often a matter of judgement, which is why the question of when a dialect counts as a separate language is hard.
An example from our data
The map treats Welsh as one language: about 724,000 speakers (Wikidata (unreferenced), approximate). Spoken Welsh differs from region to region, in sound as well as in word choice, but those differences sit inside the language and are not mapped.
English is a larger case. Our page lists it across 146 countries, with about 379 million first-language speakers (Ethnologue, 2019, approximate). Accents and dialects of English differ widely, and the map shows one language, drawn from atlases, with no layer for regional speech.
So the data answers "which languages are spoken here" and not "how do people here pronounce things". Areas are also generalisations from older atlases and do not capture local speech.
The thing people get wrong
Many people use "accent" for anything that sounds different, and "dialect" for speech they consider non-standard or lesser. Neither is accurate. Everyone has an accent, including speakers of a prestige variety. And a dialect is not a faulty version of a language: a standard language is itself one variety of its language, though it is often the one chosen for writing and schools. A person can also change their accent while keeping their vocabulary and grammar, which is why the two are worth separating.
Frequently asked questions
Does everyone have an accent?
Yes. Everyone who speaks a language pronounces it in some way, so every speaker has an accent, including speakers of a standard variety.
Can two people share a dialect but have different accents?
Yes. Dialect covers vocabulary and grammar as well as sound, so people who use the same words and grammar can still pronounce them differently.
