The spelling of the word "Blanck" has a few tricky elements to it. The "ck" at the end of the word is a common way to spell the /k/ sound after a short vowel sound. The "an" combination in the middle is pronounced as a short /æ/ sound. Finally, the double "n" is an indication that the vowel sound before it is pronounced as a short sound. So, the pronunciation of "Blanck" is /blæŋk/. It's important to pay attention to these spelling patterns so that we can accurately read and write words in English.
