What does nineteen mean?
Nineteen is the English name for the number 19, the number immediately after eighteen and immediately before twenty. It is a cardinal number used to count people, objects, years, points, and other measurable quantities. In formal writing it may appear as a numeral, 19, while the written word is especially natural in prose, speech, and phrases such as “nineteen years old.” The word belongs to the traditional English “teens,” a group covering the numbers thirteen through nineteen, though modern usage usually treats each number individually. Nineteen can also function as a noun, as in a score of nineteen or a reference to a person aged nineteen. Although the spelling can cause confusion with ninety, the difference is simply one digit: nineteen is 19 and ninety is 90.

Where does nineteen come from?
Nineteen developed from Middle English ninteene and Old English nīnteene, a compound formed from nīne “nine” and tēne, an older form related to ten “ten.” The modern form reflects the usual English pattern of forming the teen numbers from a unit word and the ending -teen. It has parallels in other Germanic languages, including Dutch negentien and German neunzehn.
