'appriser' most likely originates from Middle English and Old French roots related to valuation and notification. It is associated with Old French words like 'aprecier'/'appriser' (to value, to inform), ultimately connected to Late Latin *appretiare/*apprehendere and Latin 'pretium' meaning 'price'.

'appriser' appears as a variant formation in Middle English alongside related verbs such as 'apprise' (to inform) and 'appraise' (to value). Over time the senses and spellings diverged into modern 'apprise' (to inform) and 'appraise/appraiser' (to value/appraise), with 'appriser' surviving chiefly as an archaic or variant form.

Initially connected with notions of valuing or setting a price and with notifying (depending on the Old French source); over time English separated these senses into 'appraise' (value) and 'apprise' (inform), leaving 'appriser' as a rare/archaic or variant form referring either to someone who informs or, by variant spelling, someone who values.
