There is no consensus on whether Phoenician-Punic ever underwent the lenition of stop consonants that happened in most other Northwest Semitic languages such as Biblical Hebrew and Aramaic (cf. Hackett vs Segert and Lyavdansky). The consonant may have been "generally" transformed into in Punic and in late Phoenician, as it was in Proto-Arabic. Certainly, Latin-script renditions of late Punic include many spirantized transcriptions with "ph", "th" and "kh" in various positions (although the interpretation of these spellings is not entirely clear) as well as the letter "f" for the original *p. However, in Neo-Punic, *b lenited to v contiguous to a following consonant, as in the Latin transcription "lifnim" for *lbnm "for his son".
