The Origin and Etymology of Thereon
The word thereon dates back to Middle English and is a compound of there (meaning in or at that place) and on. Its use is tied to a tradition of creating compound directional adverbs, often used in formal or legal speech. Similar constructions include therein (in that), thereby (by that), thereto (to that), and therewith (with that).
This tradition came from a time when legal and governmental English had a heavy influence from French and Latin, encouraging precision and formality. These constructions helped avoid ambiguity by clearly linking the action or consequence to a previously stated subject.
