The word 'wealth' originates from the Old English term 'wela', which itself stems from the West Germanic root 'welon-', related to well-being and prosperity. This root is connected to the Proto-Indo-European 'wel-', meaning 'to wish, will', which also gives us the word 'well'. The suffix '-th' (from Old English '-þu') is added to form an abstract noun denoting a state or condition. Thus, the literal construction 'state of well-being' evolved semantically from general prosperity to its modern, more material-specific meaning of an abundance of valuable resources or possessions.

Structure: weal (well-being) + th (noun suffix) weal (from Old English 'wela', meaning wealth, prosperity, well-being, of Germanic origin) + th (from Old English '-þu', a noun-forming suffix indicating a state or condition).
