Question

1. describe how language changes over time?
2. what is a dialect?

Explanation:

Answer:

Language changes over time through phonetic shifts, lexical replacement, grammatical alterations, and cultural borrowing, evolving gradually across generations.
A dialect is a regional, social, or ethnic variety of a language with distinct phonological, lexical, and grammatical features, mutually intelligible with other varieties of the same language.
An example of a dialect is American English (compared to British English).
An isogloss is a geographic boundary line separating regions where different linguistic features (e.g., pronunciation, vocabulary) are used.
