What is the English meaning of the Latin term "peninsula"?

The Latin term "peninsula" literally translates to "almost an island" in English. The word is derived from the Latin roots "paene," meaning "almost," and "insula," meaning "island." A peninsula is a landform that is surrounded by water on most sides but is still connected to the mainland, which embodies the idea of being "almost" an island. This definition reflects the geographical feature itself, emphasizing its proximity to being entirely surrounded by water, yet remaining attached to land. This understanding clarifies why "almost an island" is the correct English meaning for "peninsula."
