Definition
In legal contexts, "able" functions primarily as a term of qualification — establishing that a person or party possesses the legal, financial, or physical capacity necessary to perform an act, enter a transaction, or satisfy an obligation. Its meaning shifts considerably depending on context.
1. Financial ability. In real estate brokerage law, the most litigated legal sense of "able": a prospective buyer is "able" when they have the financial capacity to complete the purchase at the agreed price and terms. A buyer who lacks financing, sufficient funds, or creditworthiness is not "able" even if they appear willing and ready. This is the operative meaning in the classic broker-commission standard — the broker earns a commission upon producing a buyer who is ready, willing, and able.
2. Legal capacity. A person is "able" in the legal sense when they are not under a disability that would prevent them from performing an act with legal effect — for example, being of legal age, of sound mind, and not otherwise legally disqualified. This usage overlaps with terms like "competent" and "capable."
3. Historical property sense (Old Law French/Law Latin). In early English law, "able" (from the Law French, cognate with Latin habilis) meant fit, proper, or suitable — as in goods described as "able to be sold," meaning merchantable. This sense largely does not survive in modern legal usage but appears in older reported cases and Year Books.

Common Language
Modern common usage (Wiktionary): Having the necessary powers or resources to accomplish a task; free from constraints preventing completion; gifted with skill, intelligence, or competence; legally qualified or competent.
Historical common usage (Webster's 1913): "Having sufficient power, strength, force, skill, means, or resources of any kind to accomplish the object; possessed of qualifications rendering competent for some end; competent; qualified; capable."
The gap between common and legal meaning is narrow in the abstract but consequential in application. Ordinary usage treats "able" as a general term of capability — physical, intellectual, or practical. Legal usage, especially in real estate and contract law, demands precision: "able" means financially able or legally capacitated, not merely willing or eager. A buyer who sincerely intends to purchase but lacks the financial means to close is, in law, not an "able" buyer, regardless of how capable they may appear in the ordinary sense.

Common Confusion
"Able" is most frequently confused with "willing" and "ready" in the real estate brokerage context, where all three terms form part of a conjunctive test. The three are distinct:
- Ready: the buyer is prepared to act immediately, without condition or delay.
- Willing: the buyer genuinely desires to complete the transaction on the offered terms.
- Able: the buyer has the financial capacity to perform — the funds, financing, or creditworthiness to close.
A broker who produces a buyer who is enthusiastic (willing) and available (ready) but financially unqualified (not able) has not, at common law, earned a commission under the traditional rule. Courts have occasionally blurred these distinctions, and some jurisdictions have modified the standard by statute or by contract; researchers should not assume uniformity.

Why It Matters in Research
The term "able" is a quiet but important variable in real estate and brokerage law research. Several traps await the unwary:
First, the ready-willing-and-able standard is not static. Its origins lie in common law agency doctrine, but many states have modified it by statute, and many modern listing agreements redefine when a commission is earned — sometimes requiring actual closing rather than mere production of a qualified buyer. Older cases applying the traditional rule may not reflect current law in a given jurisdiction.
Second, historical sources — including the Law French and Law Latin usages documented in Burrill — use "able" in the merchantability sense (ables a vendre: fit to be sold) that is entirely disconnected from the financial-capacity meaning dominant in modern brokerage law. Researchers working in pre-nineteenth-century property materials should treat "able" as a term of fitness or suitability, not financial qualification.
Third, the financial-ability question is fact-intensive and often disputed in commission litigation. What counts as sufficient financial ability — pre-approval letters, liquid assets, contingent financing — varies by case and jurisdiction. Bouvier's citation to the financial meaning is early but confirms the reading was established by the early twentieth century.
Fourth, researchers tracking the procuring-cause doctrine in MLS and cooperative brokerage disputes will find "able" doing significant work: disputes often turn not on whether a buyer was willing but on whether they were financially able at the moment the broker claims to have procured them.

Historical Dictionary Support
Burrill's Law Dictionary provides the oldest and most linguistically interesting entry: the Law French "able" (cognate with Latin habilis) meaning "fit" or "proper," illustrated by the phrase ables a vendre — fit to be sold, or merchantable. This usage is consistent with the general Old French and Anglo-Norman legal vocabulary in which "able" functioned as a general adjective of fitness. Burrill's entry is historically accurate but largely irrelevant to modern legal research outside of historical property law.
Bouvier's is the most practically significant historical source here. Bouvier defines "able" in the brokerage commission context explicitly as "financially able," citing an early twentieth-century Southern reporter decision and Walker's treatise on real estate agency. This entry is pointed and doctrinal — it does not offer a general definition but goes straight to the contested legal meaning in broker-commission cases, which is where the term most often requires precision.
Black's entry reproduced in the source materials addresses replevin rather than the "able" standard, suggesting the source pull captured an adjacent entry. This is worth noting for researchers using older Black's editions: the term "able" does not always receive its own developed entry in the major historical dictionaries, its legal content having been developed primarily through case law and treatise rather than dictionary elaboration.
Rapalje & Lawrence does not appear to address "able" directly in the sourced material. The excerpts relate to estoppel and abduction, indicating the source pull did not capture a responsive entry — consistent with the term's treatment as contextual modifier rather than a standalone doctrinal term in nineteenth-century legal lexicography.

Jurisdictional Note
The ready-willing-and-able standard for broker commissions is recognized in most U.S. jurisdictions but has been significantly modified in many. Some states require closing as a precondition to commission; others follow the traditional rule that production of a qualified buyer is sufficient. Researchers should verify which version of the rule applies in the relevant jurisdiction before relying on cases applying the common-law standard.
