Both the onset and the coda can consist of more than one consonant, also known as a consonant cluster. The combination /st/ is a consonant cluster (CC) used as onset in the word stop, and as coda in the word post. There are many CC onset combinations permitted in English phonotactics, as in black, bread, trick, twin, flat and throw. Note that liquids (/l/, /r/) and a glide (/w/) are being used in second position. English can actually have larger onset clusters, as in the words stress and splat, consisting of three initial consonants (CCC). The phonotactics of these larger onset consonant clusters is not too difficult to describe.
