trillionth
One of trillion
Trillionth is the ordinal form of trillion—the position in a sequence numbered one trillion, or one part when something is divided into a trillion equal parts.
Like other large ordinals, it often appears hyperbolically: For the trillionth time, clean your room.
In technical contexts, trillionth describes genuinely minute quantities: a trillionth of a second.
