Lapidifical is a rare word that means "turning to stone." It is derived from the Latin word "lapidis" which means "stone" and the suffix "-fic" which means "making." The spelling is fairly straightforward, with the stress falling on the second syllable, and the IPA transcription is /læpɪdɪfɪkəl/. The "a" in the first syllable is pronounced as a short "a" sound, and the second syllable features the "i" as a schwa sound, making it a lesser stress.
