How did 逸 come to feature in pleasure/idleness words?


I can't judge the reliability of <http://www.kanjinetworks.com> (and it is
probably controversial), but there the speed, movement meaning of 逸 is linked
to its claimed origins in 兎{うさぎ｝. Hence 逸する, 逸らす and such that involve some
form of movement.

However, there are also words like 逸楽, 安逸 that are linked to pleasure,
idleness etc. Where does this meaning come from?




Kanji dictionaries (漢和字典) are what to look up when confronting questions like
this. From what I've got from my dictionary:

  * My dictionary states 逸 actually is linked to 兎 in origin: "rabbits run away" -> to run, to astray.
  * For 安逸 and others, it states that they are used (in modern usage) in substitution for "佚", whose phonetic value is also "いつ". So 安逸 was originally 安佚．"佚" has no kunyomi, and its meanings include "たのしむ (to enjoy/have fun)", "なまける (to be idle)". 佚 comes from 人+失, and according to the dictionary, the origin is "まともな生活からそれたひと", so perhaps it is a good substitute even when considering the meaning.
