Final answer:
The letters 'C' and 'K' represent the /k/ and /w/ sounds in English. The sound /k/ follows the spelling pattern where it's represented as 'C' unless followed by 'I' or 'E', where it's spelled as 'K'. Letter 'W' forms a vowel sound when teamed with 'A', 'E', or 'O'.
Step-by-step explanation:
The two letters that stand for two sounds, /k/ and /w/, are the letters C and K. When analyzing the English language, it is noted that the sound /k/ at the beginning of words is usually represented by 'C' unless an 'I' or an 'E' follows it, in which case it is usually spelled as 'K'. Moreover, the letter W teams up as part of a vowel team when combined with an A, E, or O to spell a single vowel sound, like in draw, few, and low.
This provides an insight into how sounds and their associated letters are utilized in different contexts within the English spelling system. Typical pronunciation patterns show that the combination 'CK' at the end of words with a single vowel sound consistently represents the final [k], demonstrating an underlying rule in English orthography.
