What are cognates?

Cognates are defined as words that share common etymological origins. This means that these words have developed from the same ancestral language or root, leading to similarities in their form and meaning across different languages. For example, the English word "family" and the Spanish word "familia" are cognates, as they both derive from the Latin "familia."

Recognizing cognates is particularly useful in language learning and linguistics because they can help speakers of one language understand vocabulary in another, especially when the languages are related. The identification of cognates is integral to establishing connections between languages and understanding language evolution.

The other options describe different aspects of language but do not capture the essence of what cognates are. Words altered over time might involve changes in spelling, pronunciation, or meaning, but this does not specifically refer to their shared origins. Words with similar meanings might not necessarily have a common root and can exist independently in different languages. Finally, words that only exist in academic language do not pertain to cognates, as cognates can be found in everyday usage across various contexts, not just in specialized or academic terms.
