Answer:
B. Synchronic and diachronic
Read Explanation:
Synchronic and diachronic are two ways to study language, with synchronic focusing on the present and diachronic focusing on the past.
Synchronic
Definition: Existing or happening at the same time
Example: Studying the sounds of a language at a single point in time
Also known as: Descriptive linguistics or general linguistics
Diachronic
Definition: Relating to phenomena that change over time
Example: Studying how the meaning of words has changed over time
Also known as: Historical linguistics
The Swiss linguist Ferdinand de Saussure introduced the distinction between synchronic and diachronic in his 1916 book Course in General Linguistics.
Examples
Synchronic: Studying the sounds of English words like "rent" and "admit" to see what sound patterns are possible
Diachronic: Studying how the word "magic" meant "good" in youth culture in the 1980s
