What does extendible mean?
Extendible is an adjective describing something capable of being extended — that is, lengthened, widened, enlarged, or prolonged. It applies most naturally to physical objects whose size can be adjusted, such as an extendible table, ladder, or antenna, but it also covers abstract quantities: an extendible deadline can be pushed back, and an extendible budget can grow to accommodate new needs. The word derives from the Latin extendere, meaning 'to stretch out,' combined with the suffix -ible, which indicates capability or possibility. It is closely related to the variants extendable and extensible; while the three overlap considerably, extensible tends to dominate in technical fields such as software design, where it signals that a system was deliberately built to accept new features. Extendible carries a practical, functional tone and often appears in product descriptions, contracts, and everyday speech about flexible arrangements.

Etymology of extendible
Extendible comes from the Latin verb extendere, meaning 'to stretch out' or 'to spread forth,' formed from ex- ('out') plus tendere ('to stretch'). English borrowed the base verb 'extend' from Latin via Old French, and the adjective was later formed by adding the Latinate suffix -ible, indicating capability. The variant form extendable arose through the same process using the native suffix -able, and both spellings have been in use since at least the seventeenth century.
How extendible is actually used
'Extendible' and the variant spelling 'extendable' are largely interchangeable; both are common, with no strong regional preference. In technical computing contexts, 'extensible' is usually preferred.
Easily confused with extendible
'Extensible' typically describes systems or software designed to be enlarged with new capabilities, while 'extendible' more broadly means capable of being physically or literally extended.
