The spelling of the word "frostted" may seem unusual, but it can be explained through IPA phonetic transcription. The first syllable contains the sound /frɒst/, which is pronounced like "frost" with a British accent. The second syllable contains the sound /tɪd/, which is pronounced like "tid" with a hard "t" sound. Together, the word sounds like "frost-tid". While the double "t" may seem redundant, it can serve to emphasize the final consonant sound and create a more dramatic effect.
