Final answer:
The etymology of a word significantly influences its spelling. Examples include Greek-origin words altered in English and societal impacts on the evolution of language and dictionaries for effective communication.
Step-by-step explanation:
The etymology of a word, which includes its origin and history, often explains its spelling in modern English. For instance, many English words that contain the sound [k] spelled with a come from ancient Greek, where the sound was represented by the letter chi (). When these words entered English, the spelling changed from to , but the pronunciation remained as [k], which is evident in words like chorus, school, and Christmas. Additionally, changes in language reflect societal developments. For example, to adapt to contemporary inclusive language practices, many organizations have revised their style guides, such as choosing the term Black with a capital 'B' to refer to Americans of African descent, signifying a shared experience and culture.
The English dictionary evolves as the language develops, with new words being added and obsolete ones falling out of use, to ensure effective communication. The lexicon and grammar of a language are essential components, where the lexicon comprises the vocabulary and grammar denotes the rules for structuring language. This is necessary for reliable and good communication, as seen in both printed and electronic dictionaries that track these changes.
