Question 1

Why do languages die, and can they be revived?

Accepted Answer

A language dies when its last fluent speaker dies, or — more commonly and earlier — when it stops being transmitted to children. UNESCO estimates that a substantial proportion of the world's roughly 7,000 languages are endangered, with one lost every few weeks by some counts.

**Why languages die.** Almost never because speakers simply prefer another. The recurring causes are:

**Economic and social pressure.** When one language is required for education, employment, government and media, parents make a rational decision to raise children in it. This is the dominant mechanism and it operates without any coercion.

**Explicit suppression.** Many states have actively prohibited minority languages in schools, sometimes with physical punishment — documented in the histories of Welsh, Irish, Native American and Aboriginal Australian languages among many others.

**Displacement and urbanisation**, dispersing speech communities.

**Population loss** through disease, conflict or famine.

**The critical threshold is intergenerational transmission.** A language with 50,000 adult speakers and no child speakers is in worse condition than one with 2,000 speakers of all ages.

**Can they be revived?** Yes, and the evidence is stronger than sceptics assume.

**Hebrew** is the standard example — not spoken as an everyday vernacular for centuries, revived from the late nineteenth century, and now the first language of millions. It remains the most complete revival on record, though it had exceptional advantages: continuous liturgical use, extensive texts, and a motivated population concentrated in one place.

**Welsh, Māori and Hawaiian** are examples of substantial reversal of decline, achieved largely through **immersion education** — Māori *kōhanga reo* language nests and Welsh-medium schools being the decisive interventions.

**Cornish and Manx** have been revived from effectively zero everyday speakers.

**What works:** immersion schooling, official status, media, and crucially **use in ordinary domains** rather than only ceremonial ones.

Question 2

Is there a critical period for learning a language?

Accepted Answer

There is strong evidence that earlier is better, particularly for accent and grammar, but the popular version — that a window slams shut at a fixed age — overstates what the research actually shows.

Question 3

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 4

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 5

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 6

How did English become a global lingua franca?

Accepted Answer

Through two successive empires and then a network effect — and specifically not through any property of the language itself, which is a claim worth dismissing directly. The sequence: British colonial

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
