Question 1

What is the difference between a dialect and a language?

Accepted Answer

Linguistically, there is no rigorous distinction. The common quip, usually attributed to Max Weinreich, is that **"a language is a dialect with an army and a navy"** — which is flippant but captures the real answer: the boundary is political, not linguistic.

**The criterion people reach for first is mutual intelligibility** — if speakers understand each other, same language; if not, different languages. It fails immediately in both directions.

**Cases where it fails:**

**Norwegian, Swedish and Danish** are largely mutually intelligible and are called separate languages, because they belong to separate nation states.

**Chinese "dialects"** such as Mandarin and Cantonese are not mutually intelligible at all — a Mandarin speaker cannot understand spoken Cantonese — and are conventionally called dialects, because they are spoken within one state and share a written tradition.

**Serbian, Croatian and Bosnian** are close to identical and were once officially one language; political separation produced three.

**Intelligibility is often asymmetric.** Portuguese speakers typically understand Spanish better than the reverse.

**Dialect continua** break the concept entirely. Across a stretch of territory, each village understands its neighbours, but the two ends cannot understand each other. There is no point at which one language becomes another.

**What linguists actually use.** The neutral term is **variety**, covering any distinct form without ranking it. A **standard variety** is simply the one that acquired institutional backing — schooling, publishing, government — usually because it was spoken by the powerful, not because it was clearer or more logical.

**Why this matters beyond terminology:** calling something a dialect frequently carries the implication that it is a degraded version of a real language. Linguistically it is not. Every variety has a consistent grammar, and the ones stigmatised as incorrect are rule-governed in exactly the same way.

**Accent is different again** — pronunciation only, not vocabulary or grammar.

Question 2

What is the difference between a first, second and heritage language?

Accepted Answer

How and when a language was acquired, and in what environment — distinctions that matter because they predict very different patterns of ability. First language (L1, native language, mother tongue).

Question 3

What is a language family, and what is a language isolate?

Accepted Answer

A language family is a group of languages descended from a common ancestor. A language isolate is a language with no demonstrable relatives at all. How families are established. Not by similarity —

Question 4

What is code-switching?

Accepted Answer

Code-switching is alternating between languages, dialects or registers within a conversation — or even within a single sentence. It is extremely common among multilingual speakers and is frequently

Question 5

What is a creole, and how does one form?

Accepted Answer

A creole is a fully developed natural language that emerged from a pidgin — and the distinction between the two is one of the clearest and most interesting in linguistics. A pidgin arises when groups

Question 6

What is a constructed language?

Accepted Answer

A language deliberately designed by a person or group rather than one that developed through use — usually abbreviated conlang. They fall into three purposes, and confusing them produces most of the

Question 7

What is a tonal language?

Accepted Answer

One in which pitch changes the meaning of a word, not just its emphasis or emotion — the same syllable said with a rising or falling pitch is a different word entirely. How common it is. Far more
