The word "yoctoliter" is derived from the combination of two components: "yocto" and "liter".
1. "Yocto" is a prefix derived from the Greek word "oktṓ" (ὀκτώ), meaning "eight". In the International System of Units (SI), "yocto" is the prefix symbol for 10^-24. It is the smallest of the SI prefixes, indicating one septillionth (1/1,000,000,000,000,000,000,000,000) of a unit.
2. "Liter" is a unit of measurement for volume. It originated from the French word "litre", which came into use in the late 18th century and was derived from the older French term "litron".
