What does zealousness mean?
Zealousness is the noun form of zealous and describes intense enthusiasm, devotion, or eagerness in support of a cause, activity, or objective. It may be used approvingly for someone whose commitment inspires others, as in praise of a volunteer's zealousness in helping a community. It can also carry a critical implication, suggesting that the person's enthusiasm is excessive, uncritical, or difficult to moderate. The word is especially associated with religious, political, artistic, or reformist commitments, although it is not limited to those contexts. Compared with passion or enthusiasm, zealousness often stresses the force and persistence of a person's devotion. Its older associations with religious devotion remain influential in modern usage, but the word can apply broadly to any strongly pursued interest or objective.
nounThe quality of being highly enthusiastic, energetic, or devoted to a cause, pursuit, or objective. It can suggest admirable dedication or, depending on context, an excessive or uncritical intensity.
