/ˌfoʊdəˈsɛnsəˌtaɪzd/

Forms: 1900s– photosensitised, 1900s– photosensitized.

Origin: Formed within English, by compounding. Etymons: photo- comb. form, sensitized adj. at sensitize v. Derivatives

Etymology: < photo- comb. form + sensitized adj. at sensitize v. Derivatives Compare photosensitizer n. and slightly later photosensitize v.

1. Rendered sensitive to the action of light.
