* The "ch" digraph usually makes a /tʃ/ sound, as in "chair," "church," or "child."
* The /k/ sound is more common with "c" alone, as in "cat," "car," or "cake."
* There are a few exceptions. Some words borrowed from Greek or Latin keep their original pronunciation, where "ch" does represent a /k/ sound.
Here are a few examples of words where "ch" makes a /k/ sound:
* Chaos
* Character
* Chemistry
* Choler
* Chorus
* Christ
* Chronic
* Chum (archaic word for "friend")
* Echo
* Epoch
* Mechanic (sometimes pronounced with a /k/)
It's important to note that:
* The pronunciation of "ch" can vary depending on the word and its origin. For example, "ch" in "technical" can sometimes be pronounced with a /k/ sound, but often it's closer to a /tʃ/ sound.
* Dictionaries are your best guide. If you're unsure about the pronunciation of a word with "ch," consult a reliable dictionary.
