Why do people misspell this?
The variation with a space occurs due to the perception that the term consists of two separate nouns. The public often applies general phrase formation rules (glass for eyes) rather than the rules for compound words that have morphemically merged, which should be written as a single word.
Etymology & History
This word is a combination of two basic lexemes, 'kaca' (from Sanskrit 'kāca') and 'mata' (Austronesian). Terminologically, it refers to a device consisting of glass lenses to assist vision or protect the eyes.
Cultural Context
In a social context, using a space is considered a form of hypercorrection or a lack of awareness regarding the list of established compound words. Correct spelling is vital in academic and journalistic writing to maintain linguistic standard consistency.
Usage Context
“Ibu membelikan kacamata baru karena lensa yang lama sudah tergores.”
Mother bought new glasses because the old lenses were scratched.
