"Plectonephria" is a strange and complicated word, but its spelling can be explained with the help of IPA phonetic transcription. The first syllable "plec" is pronounced as /plɛk/, which rhymes with "wreck." The next syllable "to" is pronounced as /toʊ/, which rhymes with "slow." "Neph" is pronounced as /nɛf/, which sounds like "neff." Finally, the last two syllables "ri" and "a" are pronounced as /ri/ and /ə/, respectively, which together sound like "ree-uh." So, the complete pronunciation of the word is /plɛk'toʊnɛfriə/.
