The "K" Sound and Its Quirks
Before diving into word lists, it’s essential to understand the sound. The primary sound for K is the voiceless velar plosive /k/, as in kite or book. However, English etymology introduces variations. In words borrowed from Greek, the initial K often represents a hard /k/ sound before a front vowel (e.g., catastrophe, cynic), where a C might otherwise be used. Furthermore, the silent K appears in a handful of words like knight and knife, a relic of Old English pronunciation where the K was once audible. This historical layer means that while K words are phonetically straightforward for the most part, they carry tales of linguistic evolution.
