wealth

1、wealth 的根是 well：它来自古英语 weal「福祉、富裕」，而 weal 和 well 同源。所以 wealth 本义是"过得好"，钱只是过得好的一种表现。
2、-th 是把形容词拧成抽象名词的尾巴，成套记：health、length、width、depth、strength、wealth。weal 这个老词现在只剩在 commonwealth（"原指公共财富、公共福利"）里。
3、搭配：a man of wealth 有钱人、the wealth of nations 国富论、a wealth of information 大量信息（这里不指钱）。

wealth 财富

来自PIE*wel,希望，愿望，词源同will,volunteer.引申义按自己意愿，随心所欲，财富等。

wealth

wealth: [13] The now virtually defunct weal [OE] meant ‘welfare’, and also ‘riches’; it was descended from prehistoric West Germanic *welon, a derivative of the same base as produced English well. The abstract-noun suffix -th was added to it in early Middle English to produce wealth. This also originally meant ‘welfare, well-being’ as well as ‘riches’, a sense which now survives only in the compound commonwealth [15].
=> well

wealth (n.)

mid-13c., "happiness," also "prosperity in abundance of possessions or riches," from Middle English wele "well-being" (see weal (n.1)) on analogy of health.
