The Meaning of octo-
Keyword: Octo-
Definition: The prefix “octo-” comes from the Greek word “okto,” meaning “eight.” It is used to denote something that is related to the number eight or is composed of eight parts.

Etymology: The prefix “octo-” is derived from the Greek “okto,” which also means eight and is related to the Latin “octo.” The prefix has been integrated into English through scientific, mathematical, and everyday vocabulary.
Pronunciation: /ˈɒk.toʊ/ (in American English) or /ˈɒk.təʊ/ (in British English), with emphasis on the first syllable.
