Concept:A dialect refers to the specific way a language is spoken by a particular group, shaped by region, social class, or community.
Explanation:When you travel from one place to another, you notice small differences in speech between nearby villages.
As you move farther away, these differences become larger.
These variations in pronunciation, vocabulary, and grammar are called dialects.
A dialect is tied to a geographical area or a social group, not just to accent.
For example, Hindi spoken in different parts of India shows clear differences in sounds, words, and sentence structure.
Social factors like class, caste, ethnicity, or region also create dialectal differences.
Thus, a dialect describes speech characteristics of a region or a social group.
Answer:Option A – Speech characteristics of a region or a social group.
