When is the letter 'k' used to spell the (k) sound at the end of a word?

The correct understanding of when the letter 'k' is used to spell the (k) sound at the end of a word is associated with its appearance after consonants or vowel digraphs. In English, the letter 'k' is often used after these letter types to create the (k) sound. For instance, in words like "park" or "milk," the 'k' effectively follows a consonant or a vowel sound that can be represented as a digraph, demonstrating that this is a common phonetic structure.

Using 'k' after vowels only would not account for many instances where it appears, especially when followed by consonants, which is a valid phonetic construction in the English language. Likewise, stating that 'k' is used only at the beginning of a word contradicts its frequent usage in final positions, as evidenced by countless examples in English vocabulary. Furthermore, limiting its use to only multi-syllable words overlooks the simple one-syllable words where 'k' appears at the end, such as "book" or "snack." Therefore, the choice highlighting its use after consonants or vowel digraphs accurately reflects the understanding of phonetic rules in English spelling.
