These are sounds formed with the front part of the tongue on the alveolar ridge, which is the rough, bony ridge immediately behind and above the upper teeth. The initial sounds in top, dip, sit, zoo and nut are all alveolars. The symbols for these sounds are easy to remember – [t], [d], [s], [z], [n]. Of these, [t] and [s] are voiceless whereas [d], [z] and [n] are voiced.

 It may be clear that the final sounds of the words bus and buzz have to be [s] and [z] respectively, but what about the final sound of the word raise? The spelling is misleading because the final sound in this word is voiced and so must be represented 28 The Study of Language by [z]. Notice also that despite the different spelling of knot and not, both of these words are pronounced with [n] as the initial sound. Other alveolars are the [l] sound found at the beginning of words such as lap and lit, and the [r] sound at the beginning of right and write.
