Q.Discuss the essential features of a Negotiable Instrument. What makes an instrument truly 'negotiable' as opposed to merely 'transferable'?

The essential features build up to one defining idea: a negotiable instrument's transferee can get a title BETTER than the transferor's own, which an ordinary transferable debt never allows.

Work through each feature and then contrast negotiability against ordinary transferability (assignment of an actionable claim) to show the difference.

Essential features of a Negotiable Instrument:

1. Written and signed — the instrument must exist in writing and be signed by the party who makes/draws it.
2. Unconditional promise or order to pay — payment cannot be made contingent on any condition or event.
3. A certain sum, in money only — the amount must be fixed, and payable in money, never in goods or services.
4. Payable on demand or at a certain/determinable future time — the time for payment must be fixed or capable of being made certain.
5. Free transferability (negotiability) — the instrument passes from person to person by delivery, or by endorsement and delivery.
6. A good-faith transferee for value gets a good, and potentially BETTER, title — this is the defining feature, discussed below.
7. Statutory presumptions apply (Section 118) — e.g. that the instrument was made for consideration, that it bears the date it shows, and about the order in which endorsements were made — until the contrary is proved.

Negotiable vs. merely transferable — the real distinction. Almost anything can, in a loose sense, be 'transferred' — for instance, an ordinary debt can be ASSIGNED from a creditor to a third party. But an assignee of an ordinary debt only ever steps into the assignor's own shoes: if the assignor's title was defective (e.g. the debt was obtained by fraud, or was already time-barred), the assignee's title is EQUALLY defective — the legal maxim is nemo dat quod non habet ("no one can give what they do not have").

A negotiable instrument breaks this rule, and that is precisely what negotiability means in law. If a person takes a negotiable instrument as a Holder in Due Course — for consideration, before it is overdue, in good faith, and without notice of any defect in the transferor's title — that person gets a title FREE of the defects that may have existed earlier in the chain, even if an earlier holder had obtained the instrument by fraud, theft, or without any consideration at all. This is what makes a negotiable instrument commercially far more valuable and liquid than an ordinary debt: a merchant accepting a bill of exchange or a cheque in the ordinary course of business does not need to investigate the entire history of who held it before, because the law itself protects a good-faith taker.

In short: mere 'transferability' only ever passes on exactly the title the transferor had; true 'negotiability' can actually CURE a defective title in the hands of a protected good-faith taker — and that curative effect is the single feature the whole of this unit's later topics (Holder in Due Course, negotiation, endorsement) exist to protect and regulate.

An alternate way to organise the answer is around the 'nemo dat quod non habet' contrast: state the rule for ordinary transfers first, then show negotiability as the deliberate statutory EXCEPTION to that rule for the three named instruments.

A frequent error is listing only the surface features (written, signed, certain sum) and never actually explaining what negotiability itself MEANS — the examiner is specifically testing whether the student understands the good-faith-title-curing effect, not just the formal requirements of the instrument.
