Pronunciation: [ɛkstˈɛnsəbə͡l] (IPA) 
The word "extensible" is spelled as /ɪkˈstɛnsəbəl/. The prefix "ex-" means "out" or "away," while "tens" comes from the Latin word "tensus," meaning "stretched." The suffix "-ible" means "able to be." Therefore, "extensible" means "able to be stretched out or extended." The unusual spelling of this word is due to the combination of the prefix and the Latin root, making it a somewhat challenging word to spell correctly.

The word "extensible" originated from the Latin term "extendere", which is a combination of "ex" meaning "out" or "beyond", and "tendere" meaning "to stretch". "Extendere" evolved into the Old French word "extendre" and eventually into the English word "extend" by the 14th century. The adjective form, "extensible", emerged in the 17th century to describe something that is capable of being extended or stretched out.
