The word "Torpifying" is spelled with the letter combination "fi" rather than "phy" because the "f" sound is already represented by the letter "f" and does not need the addition of the letter "h." The IPA phonetic transcription of this word is /ˈtɔːpfʌɪɪŋ/ which breaks it down into individual sounds. The stress on the first syllable is shown by the apostrophe before the /t/. The word refers to the process of causing someone or something to become sluggish or inactive.
