The compound adjective "ten-dollar" is a modern English formation combining a native number with an internationally adopted currency term. "Ten" is a fundamental numeral preserved from Proto-Indo-European, maintaining its quantitative meaning. "Dollar" has a more complex journey, originating as a 16th-century German coin named for its place of minting. The fusion of these two elements follows a straightforward English compounding pattern, where a number directly modifies a noun to create a descriptive term specifying exact monetary value, a common and productive method for pricing and valuation.

Structure: ten (number) + dollar (monetary unit) - ten: From Old English tēn, tīen, from Proto-Germanic tehun, from Proto-Indo-European déḱm̥t. A cardinal number. - dollar: From Low German daler, a shortened form of Joachimstaler, a coin from the silver mines of Joachimstal (St. Joachim's Valley). The term entered English via Dutch daler and refers to a standard unit of money.
