A consonant digraph is a combination of two consonants that represent a single sound.
Here are some examples:
* "sh" as in "ship"
* "ch" as in "chair"
* "th" as in "thin" or "the"
* "ph" as in "phone"
* "wh" as in "where"
* "ck" as in "duck"
There are many other consonant digraphs, and they can be tricky for young learners to master.
