On spectrograms, this is the highest-frequency English phoneme with a noisy “TV static” appearance. The sonority sequencing principle is most often violated by clusters that begin with this phoneme. (15[1])In Maori borrowings, this is the frontmost phoneme that becomes /h/, which also occurs in Spanish syllable-final debuccalization. A prothetic vowel is added to word-initial clusters starting with this phoneme in Hindi, Persian, and (*) Western Romance (-5[1])languages. Most Latin American Spanish dialects, but not Peninsular ones, no longer distinguish the dental /θ/ (“theta”) from this consonant. In English, this is the only phoneme that can occur before a nasal in an onset or begin a three-consonant onset. The most common fricative across languages is this voiceless sibilant. For 10 points, name this consonant that is also the most common pronunciation of the usual English (10[1])plural suffix. ■END■
