appraise: [15] Originally, appraise meant simply ‘fix the price of’. It came from the Old French verb aprisier ‘value’, which is ultimately a parallel formation with appreciate; it is not clear whether it came directly from late Latin appretiāre, or whether it was a newly formed compound in Old French, based on pris ‘price’. Its earliest spellings in English were thus apprize and apprise, and these continued in use down to the 19th century, with the more metaphorical meaning ‘estimate the worth of’ gradually coming to the fore.

From the 16th century onwards, however, it seems that association with the word praise (which is quite closely related etymologically) has been at work, and by the 19th century the form appraise was firmly established. Apprise ‘inform’, with which appraise is often confused (and which appears superficially to be far closer to the source pris or pretium ‘price’), in fact has no etymological connection with it.

It comes from appris, the past participle of French apprendre ‘teach’ (closely related to English apprehend).
