How Do You Spell KASTER?
Pronunciation: [kˈastə] (IPA) 
The word "kaster" is uncommon in English, however, it can refer to either a molding tool or a surname. Its correct pronunciation is /ˈkæstər/, with stress on the first syllable. The spelling can be explained by following the rules of English phonetics, where the letter "a" is pronounced as a short vowel sound /æ/ and "s" followed by "t" produces the consonant cluster /st/. The final letter "er" indicates that it is a noun, and therefore, the spelling remains consistent with the suffix.
