Prizable comes from prize (verb, 'to value highly', from Old French preisier 'to praise, value', from Late Latin pretiare, from Latin pretium 'price, value') + the suffix -able. The historical chain includes Old French preisier and Latin pretium. The quoted older senses, "to value highly", "to praise, value", and "price, value", supply the semantic anchors for prizable. The formation is best read as suffixal, compound, and borrowed: the word prizable carries its older form-history into a compact English lexical shape. In present English it is used as a adj, "worthy of being valued or esteemed". Related English forms include prize, prized, and appraise. The result is a adj whose etymology preserves both the older form and the later English specialization.
