In the word 'buckle', how is the /k/ sound represented?

The /k/ sound in the word 'buckle' is represented by the letter 'C.' In English, the letter 'C' can represent the /k/ sound when it appears before letters such as 'a,' 'o,' and 'u,' as seen in 'buckle.' While 'K' and 'CK' can also represent the /k/ sound in different contexts, in this specific instance, it is the 'C' that is responsible for producing that sound. The presence of 'CK' in other words denotes a different spelling convention as well, but in the case of 'buckle,' the crucial representation of the /k/ sound relies specifically on the 'C.' Thus, understanding the various ways sounds can be represented in written language helps in decoding and spelling words accurately.
