The word "phoroplast" is spelled with a "ph" at the beginning, which represents the sound /f/ in the International Phonetic Alphabet. The following "oro" is spelled how it sounds, with the two vowel sounds /ɔ/ and /oʊ/. The final "plast" has the same spelling as the word "plastic," but it represents a different meaning. "Phoroplast" refers to a substance used in entomology to preserve insect specimens. Its spelling reflects the combination of Greek roots phor-, meaning "bearer," and -plast, meaning "something that molds or gives form."
