thereof
UK: ðɛərˈɒv | US: ðɛrˈʌv
adv. of or concerning the thing just mentioned
adv. from that cause or origin
The word "thereof" is a compound of "there" (Old English þǣr, meaning "in that place") and "of" (Old English of, indicating possession or relation). It emerged in Middle English as a straightforward combination to denote "of that" or "from that," often used in legal or formal contexts to refer back to something previously mentioned. The morphemes retain their original meanings, with "there" anchoring spatial/abstract reference and "of" linking ownership or association.
