On spectrograms, this is the highest-frequency English phoneme with a noisy “TV static” (15[1])appearance. The sonority sequencing principle is most often violated (15[1])by clusters that begin with this phoneme. In Maori borrowings, this is the frontmost phoneme that becomes /h/, which also occurs in Spanish syllable-final (-5[1])debuccalization. (15[1]-5[1])A (15[1])prothetic vowel is added to word-initial clusters starting with this phoneme in Hindi, Persian, and (*) Western Romance languages. Most Latin American Spanish dialects, (-5[1])but not Peninsular ones, no longer distinguish the (10[1])dental /θ/ (-5[1])(“theta”) from this consonant. (10[2])In English, this is the only phoneme (10[1])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, (10[1])name this consonant that is also the most common pronunciation of the usual English plural suffix. (10[2])■END■ (10[3]0[1])
