Dialect
From Halbeeg, the open encyclopedia · Af-Soomaali
138 languages
A dialect is a particular way of speaking used by a group of people, distinguished from other varieties of the same language by differences in pronunciation, vocabulary, and sometimes grammar. Speakers of two dialects of the same language can generally understand each other, although there may be clear differences.
Dialects arise from geographic separation, social differences, and the history of contact between groups. When communities settle in different places and have reduced interaction with each other, speech changes occur differently in each location, and dialects emerge.
The boundary between dialect and language
The boundary between dialect and independent language is not a matter of settled linguistic definition. The practical criterion is 'mutual intelligibility': if people understand each other, the varieties are called dialects of the same language. However, political and national considerations often determine what name is used; some mutually intelligible varieties are designated separate languages, while others that are not mutually intelligible are called dialects.
Types of variation
Linguistics distinguishes geographic dialect (tied to location) from sociolect (tied to education level, occupation, or social class). There is also idiolect, the speech pattern of a single individual. Features that mark differences include accent, vocabulary choice, and particular grammatical patterns.
Standard language and dialect
Most languages develop a standard form used in schools, government, and media. This standard typically comes from one dialect chosen for political or economic reasons, though it is not linguistically 'better' than other varieties. Non-standard dialects generally persist in everyday speech.
Research
Dialectology uses surveys and speech recordings to track features across different areas. Findings are mapped using isoglosses, lines marking the boundary of a particular feature. These lines often do not align perfectly, showing that dialect transitions are gradual rather than sharp.
