Etymology

"Thirty" derives from Old English "þrītig," combining "þrīe" (three) and "-tig" (a suffix denoting multiples of ten). "Nine" comes from Old English "nigon," rooted in Proto-Germanic "*newun." The compound "thirty-nine" follows the standard English pattern for forming numbers between 21–99 by combining the tens and units with a hyphen. This structure reflects the Germanic base of English numerals, where additive phrasing ("thirty and nine") evolved into hyphenated forms.
