Simplify to clarify.
If you can answer a question completely in 7 words, don’t use 8. If you can use the most simple language that even a child can understand, don’t use fancy words to possibly confuse others. If you do so, you’re doing so out of your own ego. You’re signaling to others “how smart you are.” Because if you were truly smart, you would not feel the need to prove it to others. Instead, your main focus would be to pass along information as clearly and concisely as possible, so that everyone listening understands and can put it into practice.
