🔍 What is a Prefix? A prefix is a group of letters added to the beginning of a word to change its meaning. 💡 Common Prefixes and Their Meanings:
• un-: not (e.g., unhappy)
• re-: again (e.g., rewrite)
• pre-: before (e.g., preheat)
• dis-: not, opposite of (e.g., disagree)
• mis-: wrongly (e.g., misspell)
