Yôthēr (יוֹתֵר) means more, advantage, excess, remainder. From yāthar (to remain, to be left over). It appears in Ecclesiastes as a key philosophical term.
Ecclesiastes 6:8: 'What advantage does a wise person have over a fool?' Ecclesiastes 6:11: 'The more the words, the less the meaning.' Ecclesiastes 7:11: 'Wisdom, like an inheritance, is a good thing and benefits those who see the sun; for wisdom is a shelter... the advantage of knowledge is this: wisdom preserves those who have it.' The Preacher wrestles with ultimate value — what truly matters 'under the sun.' His conclusion: fear God and keep His commandments (12:13). All other advantages are vapor (hevel) without this foundation.
