Although I have not had much practice, I felt ___ in my ability to train the puppy. Which of the following is the correctly spelled word to complete the sentence?

The word that correctly completes the sentence is "confident." This term means having a strong belief or assurance in one's abilities or qualities. In the context of the sentence, the speaker expresses a belief in their ability to train the puppy, despite limited practice.

The other options do not fit the context of the sentence. "Confidante" refers to a person with whom one shares a secret or private matter, typically a trusted friend, and does not relate to self-assurance. "Confidents" is the plural form of "confident," but it does not convey a sense of belief in one’s own abilities. "Confidense" is a misspelling of "confidence," which also does not serve as an adjective to describe the state of being assured in one's abilities. Overall, "confident" is the only word that appropriately communicates the intended meaning in the sentence.
