What does conjugable mean?
Conjugable is an adjective meaning capable of being conjugated. In grammar, it describes a verb that can take the full range of inflected forms demanded by a language's conjugation system — changes in person, number, tense, voice, or mood. It applies naturally to languages like Spanish, French, German, or Latin, where verbs are heavily inflected, and far less obviously to English, whose verbs have shed most endings and are often described as weakly conjugable by comparison. A second, much rarer sense appears in mathematics, where something may be called conjugable if it can be put into a conjugate form, as with radicals or algebraic numbers. The word derives from Latin conjugare, 'to join together', via the same root that gives us conjugate and conjunction. Conjugable is a technical term: you will meet it in linguistics textbooks and grammars rather than everyday speech, where a phrase like 'can be conjugated' does the same work more plainly.
Capable of being conjugated; able to undergo the inflectional changes characteristic of a conjugation class.
"The textbook listed all the conjugable verbs in the Romance languages chapter."
Used almost solely in linguistic and grammatical description.
In mathematics, expressible in or reducible to a conjugate form.
"These surds are conjugable, allowing the expression to be rationalised."
A rare, specialist sense confined to mathematical contexts.
Every verb in Latin had to be 'conjugable' — but English verbs barely bother, which is why this tidy little adjective is so rare outside linguistics.

Etymology of conjugable
Conjugable comes from the Latin verb conjugare, 'to yoke together' or 'to join', formed from com- ('with, together') plus iugare, from iugum, 'yoke'. The idea behind the grammatical term is that a verb's various forms are 'joined' into a single family. The word passed into scholarly Latin and then into modern European languages as an adjective describing verbs fit for conjugation; it entered English through the learned tradition of grammar writing. It shares its root with conjugate, conjunction, conjugal, and ultimately with words such as yoke and join, all pointing back to the notion of binding things together.
How conjugable is actually used
A formal, technical term found almost exclusively in linguistics, grammar reference works, and higher mathematics. It carries no emotional connotation. In ordinary conversation it would sound pedantic; speakers normally just say a verb 'can be conjugated'. The word is uncommon enough that many dictionaries omit it entirely, and writers should prefer plainer phrasing except when addressing a specialist audience.
