The spelling of the word "tricarpellites" is quite complex. It begins with the prefix "tri-", meaning three, followed by "carpel", referring to the female reproductive part of a flower. The suffix "-ite" indicates a mineral or rock. The combination of these elements gives us "tricarpellite", a mineral that contains three carpels. The added "s" at the end makes it plural. The IPA phonetic transcription for "tricarpellites" is /ˌtrɪkɑːpəˈlaɪts/, emphasizing the stress on the third syllable.
Fossil nut-like fruits from the London clay-so called from their consisting of three carpels or seed-cells.
