UK: eɪtθ ɡreɪd | US: eɪtθ ɡreɪd
adj. relating to the eighth year of formal education, typically for students aged 13–14
n. the eighth level of primary or secondary school
The word combines "eighth," derived from Old English "eahtoþa" (related to "eight"), with "grade," from Latin "gradus" (step/degree). The hyphenated form emerged in the 19th century to specify educational stages, reflecting a systematic numbering of school years. The morphemes retain their original meanings while forming a compound adjective/noun.
