IPA: /ˌtɛrətoʊdʒəˈnɪsɪti/
KK: /tɛrəˌtoʊdʒəˈnɪsɪti/
The ability of a substance to cause physical defects or abnormalities in a developing embryo or fetus.
Certain medications have teratogenicity, which can lead to serious birth defects if taken during pregnancy.
Teratogenicity → It is formed from "terato-" (from Greek "teratos", meaning monster or malformation) and "-genic" (from Greek "genes", meaning born of or produced by) and "-ity" (meaning the state or condition of). The word refers to the condition of being capable of causing malformations or monsters in developing organisms.
Think of 'terato-' meaning monster or malformation, and '-genic' meaning produced by — this helps you remember that teratogenicity refers to the condition of causing malformations.
