Close - a 'conjugated' verb is a verb with a bit added or changed, to affect its grammar; another word for it would be 'bare infinitive'. So "take" is an unconjugated verb, and "took", "taken" or "takes" are unconjugated forms. I wouldn't call adding 'can' conjugating, but some teachers might. And, etymologically, many inflected verbs (ones with endings or changes that mark a change in grammatical function) turn out* to have been originally separate words added on.
* Etymological note, that can be safely ignored :
The simple future in most Romance languages gives many examples: The first conjugation -abo endings of the Classical Latin future were replaced in Vulgar Latin by habere de <infinitive> - in Spanish, for example amabo -> hé de amar - in that case, "amar" was often replaced by "querer", so I'll switch to that version for the rest of the example - hé de querer -> quereré; (in medieval texts you can see a transitional form, with the -é future written as two words: <infinive> hé**). Both versions still exist today. The three-word so-called 'analytical' one is less common than the one-word future, but is used in some contexts - especially political rhetoric. I'll leave it to a native Spanish speaker to say more about this usage. My Spanish is "best before 1975" .
**PS In Portuguese it's shown when a simple future (say acharei) has an object pronoun inserted: achá-lo-ei .
