Synonym discussion
Sense: adjective/1
All four describe situations where something is not firmly settled, but they differ in scope and context. Negotiable is the most specific: it applies to terms, prices, or conditions that both sides can work out before an agreement — for example, a job offer where the start date is negotiable. Flexible is broader: it can describe a person's schedule, materials, or even someone's attitude ('my boss is flexible about working hours'). Open to discussion is more transparent and conversational, often used when inviting a counterpart to propose changes ('the payment plan is open to discussion'). Debatable shifts the meaning toward uncertainty or doubt rather than compromise, so it fits opinions ('whether that approach works is debatable') rather than business terms. Use negotiable when talking about agreements and contracts; use flexible for personal arrangements; use open to discussion when you want to invite proposals; and use debatable only when the point is in question.

Etymology
Negotiable comes from the Latin verb negotiari, meaning 'to carry on business'. This breaks down into nec (not) and otium (leisure) — so the root idea is 'not at leisure, being busy with trade'. The word passed through French into English, and by the 1700s it was being used in legal and commercial contexts to describe documents that could be traded or transferred. The broader sense — 'open to discussion' — emerged in the early 1900s as negotiation became a common part of everyday agreements.
