Small English mistakes can make you sound unprofessional. And the worst part? You might not even realize you're making them! Imagine this… You're in an important meeting. You say, "I am agree." No one corrects you, but they notice the mistake. Or you send an email saying, "I need an advice." It seems small, but to a native speaker, it sounds wrong. Little mistakes like these can affect how people see you. So, let’s fix them right now. Here are 10 common mistakes that professionals make—and how to correct them: ❌ "I am agree" → ✅ "I agree" ❌ "Can you repeat again?" → ✅ "Can you repeat?" ❌ "I am working in this project." → ✅ "I am working on this project." ❌ "I have a good news." → ✅ "I have good news." ❌ "Let’s discuss about this." → ✅ "Let’s discuss this." ❌ "I will explain you." → ✅ "I will explain to you." ❌ "I need an advice." → ✅ "I need advice." ❌ "He is married with Sarah." → ✅ "He is married to Sarah." ❌ "It depends of the situation." → ✅ "It depends on the situation." ❌ "I didn’t knew that." → ✅ "I didn’t know that."
