FCE / B2 First Word Formation Practice Exam

The adjective form of "comfort" is "comfortable." This word is derived from the noun "comfort" and is used to describe something that provides ease, relaxation, or physical well-being. For instance, when we say a chair is comfortable, we mean it offers a pleasant seating experience.

"Comforting," while an adjective as well, generally describes something that gives comfort in a more active sense, such as a comforting hug or soothing words, rather than describing a state of being comfortable. "Comforted" is a past participle form that indicates a state of having received comfort, while "comfortablely" is not a standard form in English; the correct adverbial phrase would typically be "in a comfortable way." Therefore, "comfortable" is the most appropriate choice to represent the adjective form of "comfort."
