Meaning & origin
Trillion is a striking modern coinage that first appeared on U.S. birth records in 1990, during a period when parents began embracing unconventional word names. As a numerical term, it belongs to a small cluster of names like Million and Billion, chosen for their memorable, grandiose quality rather than any traditional meaning. The name has been rising in use since 2007, and reached its peak rank so far in 2025 at number 5208, with about 1 in 94,893 boys receiving the name that year. Its rarity makes it a distinctive choice, though it remains far outside the mainstream, with no strong association with any particular region of the country.
Trillion is a modern invented name inspired by the number term 'trillion' (1,000,000,000,000), which itself comes from French 'trillion' (from tri- 'three' + million). It emerged as a given name in the United States in the early 1990s, part of a trend of using numerical or unit-based names for their bold, distinctive sound.
