extensible

The word "extensible" is built upon the Latin verb extendere, meaning "to stretch out". This verb itself is a compound of the prefix ex- ("out") and tendere ("to stretch"). The root tendere traces back to the Proto-Indo-European root ten-, meaning "to stretch, extend", which is also the source for a wide array of English words like "tension", "tendon", and "tent". The suffix -ible, of Latin origin, was added to form an adjective meaning "able to be stretched out". Over time, while retaining its core physical meaning, "extensible" has been prominently adopted in computing to describe systems or software whose functionality can be stretched out or expanded through modular design.

Structure: ex (out) + tens (stretch) + ible (capable of) - ex: Latin origin, a prefix meaning "out of, from, thoroughly". - tens: Latin origin, from the root of tendere (to stretch). - ible: Latin suffix -ibilis, forming adjectives meaning "capable of, fit for, able to be".
