extendable

The word "extendable" is built upon the core Latin verb tendere, meaning "to stretch." This root is prefixed with ex- ("out"), creating the sense of "stretching out." The suffix -able, entering English via Old French from Latin -abilis, denotes capability. Thus, the literal construction "capable of being stretched out" directly informs its modern meanings, from describing physical objects that can be lengthened to systems designed for future expansion. The semantic journey from the physical act of stretching to the abstract concept of capability for enlargement is a clear and logical progression.

Structure: ex (out) + tend (stretch) + able (capable of) - ex: A Latin prefix meaning "out, out of, from." - tend: From Latin tendere, meaning "to stretch, extend." - able: A suffix of Latin origin via Old French, forming adjectives meaning "capable of, fit for, or worthy of being acted upon."
