Synonym discussion
Sense: noun/1
Nineteen and the number 19 refer to the same value and can be used interchangeably as nouns (say nineteen out loud vs. say the number 19 out loud). The spelled-out form nineteen is preferred in formal writing, while 19 is common in tables, addresses, and informal notes. The ordinal nineteenth (e.g., the nineteenth person) indicates position in a sequence, not quantity. Use nineteenth for order (the nineteenth floor) and nineteen for count (nineteen floors).

Etymology
Nineteen comes from the Old English word nigontiene, which was formed by combining nigon (nine) and tien (ten), literally meaning 'nine and ten'. Over centuries of use, the spelling and pronunciation shifted through Middle English nynetene to the modern form nineteen.
