eclipse:  From the point of view of the observer, an object which has been eclipsed has ‘gone away’ – is no longer there. And that in fact is the etymological foundation of the word. It comes, via Old French and Latin, from Greek ékleipsis, a derivative of ekleípein ‘no longer appear or be present’. This was a compound verb formed from the prefix ek- ‘out, away’ and leípein ‘leave’ (a distant relative of English leave).
Its adjectival derivative, ekleiptikós, passed into English as ecliptic , which was applied to the apparent path of the Sun relative to the stars because that is the line along which eclipses caused by the moon occur. => leave
