Keelekriteeriumid

Keelekriteeriumid, or language criteria, are a set of guidelines used to determine the linguistic characteristics of a language. These criteria are essential for identifying and classifying languages, as well as for understanding the relationships between different languages. The most commonly used keelekriteeriumid include:

1. Mutual intelligibility: This criterion refers to the ability of speakers of different languages to understand each other when communicating. Languages that are mutually intelligible are often considered dialects of the same language.

2. Isoglosses: These are lines on a map that separate different linguistic features. For example, the line that separates speakers of English with the "r" sound from those who do not is an isogloss.

3. Lexical criteria: This involves comparing the vocabulary of different languages. Languages with a high degree of lexical similarity are often considered to be closely related.

4. Phonological criteria: This criterion looks at the sound systems of different languages. Languages with similar sound systems are often considered to be related.

5. Grammatical criteria: This involves comparing the grammatical structures of different languages. Languages with similar grammatical structures are often considered to be related.

6. Historical criteria: This involves looking at the historical relationships between languages. Languages that have evolved from a common ancestor are often considered to be related.

These keelekriteeriumid are not always definitive, and there can be overlap and exceptions. For example, two languages may have a high degree of lexical similarity but differ significantly in their phonological and grammatical structures. In such cases, linguists may use a combination of criteria to make a determination.
