negotiable

The word 'negotiable' originates from the Latin verb negotiari, meaning 'to carry on business'. This verb itself is a compound of neg- ('not') and otium ('leisure'), literally painting a picture of business as an activity that is 'not leisure'. The core concept evolved from this literal sense of being occupied with work to the more abstract idea of conducting dealings or discussions. The suffix -abilis was added to form the adjective, shifting the meaning from the act of transacting to the quality of being open to transaction or discussion. Thus, the modern sense of 'able to be negotiated' retains the ancient link between business, the absence of idleness, and the process of reaching an agreement.

Structure: neg (not) + oti (leisure) + able (capable of) neg (Latin origin, a prefix meaning 'not'); oti (from Latin otium, meaning 'leisure, ease'); able (from Latin -abilis, an adjective-forming suffix meaning 'capable of, fit for').
