Carriable comes from carry + -able. Carry is from Anglo-Norman carier ('to transport in a vehicle'), from Latin carrus ('wagon, cart'), of Gaulish origin. The historical trail runs through carier in Old French and carrus in Latin. Morphologically, carriable is transparent: it draws on carry + -able. Used as an adjective, carriable now means "able to be carried or transported", so the present definition can be read against the older forms and meanings. The same lexical family is also visible in related forms such as carry, carriage, and carrier. The result is a borrowed or transmitted form whose modern spelling carries a compact record of its route into English.
