Less common meanings
- 4Sound in body and physically strong; robust and in good health.
Note
The bodily sense is now obsolete in standard English and lives on only in dialect. Its trace survives in able-bodied and in phrases like every able body, where the word means fit and sound rather than skilled. Outside historical or regional writing, fit or strong is the safer choice: "only half the men are fully able" now reads as old-fashioned.

- 5Suitable or competent; fit for a particular purpose or role.
Note
Fit for a purpose rather than skilled at it. New Jersey's colonial Concession and Agreement of the 1660s grants land for "every able man servant" sent out armed, meaning men fit for service. It is now obsolete, and suitable or fit carries the meaning.

- 7Rich and well-to-do; having ample money, land, or other property at one's command.
Note
Money is another kind of means. In this obsolete use, an able family was simply a wealthy one, with the means to pay, lend or give. Modern readers easily take it as "talented," so in older texts check whether property or rank is in view. Well-to-do or well off says it today.

- 8Liable to something; likely to undergo or suffer it.
Note
Here the word looks at what may befall someone, not at what they can do: it meant liable to something, likely to suffer it. This sense is obsolete and dialectal, so recognize it in old regional writing but do not use it; liable or prone is the modern word. Watch for the trap: in such texts, able to may mean prone to rather than capable of.

- 9To make a person capable of something; to enable.
Note
The obsolete verb that enable has since taken over. To able someone was to make them capable, as in abled him to study. It is the causative partner of the core adjective: the verb confers what the adjective describes. A reader who meets it in early texts can safely read it as enable.

- 10To give power to; to strengthen or reinforce; to confirm.
- 11To make ready; to prepare a person or thing for use or action.
Note
Middle English made a verb directly from the adjective, ablen, and this obsolete sense is its plainest: to able something was to make it ready. It is transitive, so it takes a direct object (able the horses), and it inflects regularly as ables, abling, abled. In anything but deliberately period writing, prepare does the job.

c. 1603, William Shakespeare, “The Tragedie of King Lear”Note
The obsolete verb's most memorable use is Shakespeare's, in King Lear: "None does offend, none… I'll able 'em." To able people here is to vouch for them, staking one's own credit on their innocence. Unlike vouch for, it takes its object directly, with no preposition. Anyone quoting the line should read able as "warrant," not "enable."

Origins
It comes from Middle English able, borrowed via Old Northern French able (a variant of Old French abile, habile), from Latin habilis ("easily managed or handled; apt; skillful"), formed from habeō ("to have, possess") plus the suffix -ilis. The native Old English verb for being able, magan, survives as may, which developed a different meaning.
