1.
fun; enjoyment; the pleasure of doing something
The quality of being enjoyable, treated as a thing that can be known, conveyed, or tasted. Formed from 楽しい plus the noun-making suffix さ, so it names the degree of enjoyment rather than a particular occasion of it.
The さ form of 楽しい. Adding さ to an i-adjective stem turns it into a noun naming the quality itself: 高い → 高さ (height), 面白い → 面白さ (interest).
