Here is a pair of context clues worksheet for articulate used as an adjective and a verb. These documents require, I think, a bit of exposition: these are complicated words, and the worksheet itself is keyed to specific meanings of these words and the parts of speech for which they function. Let’s start with the adjective: the sentences in the first document seek to move student toward inferring the adjectival definition of articulate as “expressing oneself readily, clearly, or effectively.”
The verb is another matter. First of all, it is used both intransitively and transitively. Intransitively, it means “to utter articulate sounds,” “to utter clear and understandable sounds,” and, less relevantly to the matter at hand, “to become united or connected by or as if by a joint” (e.g. the articulated buses one sees in big-city public transportation systems worldwide). Transitively, articulate means “to give clear and effective utterance to,” “put into words,” “to utter distinctly,” and “to give definition to (as a shape or object).” But it too carries the meaning” to unite by or as if by means of a joint” as above.
In any case, the second page of this document seeks to elicit the more common definitions of the verb, which is, transitively “to give clear and effective utterance to,” and “put into words.” And that’s more than enough said about the use of articulate (don’t forget the stress shifts to the final syllable for the verb) as a verb and as an adjective.
If you find typos in these documents, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
