What does keener mean?
“Keener” is the comparative form of “keen” and is used when one quality is being compared with another. Most often it describes greater eagerness, enthusiasm, or alertness: a participant may be “keener” to win, and a reader may be “keener” to learn. It can also mean sharper or more acute, as in “a keener edge” or “a keener sense of hearing.” The noun “a keener,” which is less common, denotes a keen or especially enthusiastic person. The word is standard in both British and American English, though alternatives such as “sharper” or “more keen” may occasionally sound more natural in particular contexts. Its usefulness lies in combining comparison with several related strengths: keenness can describe both intensity of feeling and sharpness of perception, and “keener” lets a speaker place one person or thing above another without simply repeating “more.”
