Phonetics and the IPA 4, Exercise 2: English click-like sounds "tsk tsk" (tut-tut): a dental click [ǀ]. The tongue tip pulls away from the back of the front teeth. The horse "tchick": a lateral click [ǁ]. Air is sucked in at the side of the tongue (the molars) and the sound is released at the side. How to tell: look at where the front closure is released. Teeth = dental, the sides of the tongue = lateral. (Wikipedia: the alveolar "pop" [ǃ] is the "clip-clop" horse sound.) Caveat from the source: these English sounds are not full click consonants, because they lack the back release needed to combine with vowels.
