Conventionally means doing something in the usual, traditional, or widely accepted way. When you spell a word conventionally, you spell it the way most people do, following standard rules. When someone dresses conventionally, they wear clothes that fit normal expectations for the situation.

Sometimes conventionally simply describes doing things in a standard way, like solving a math problem using the method taught in class. Other times it can suggest someone is sticking to tradition even when new options exist. A conventionally built house uses familiar materials and designs, while an experimental architect might try something unusual.

When people say someone thinks unconventionally, they mean that person approaches problems differently than most others do. Einstein thought unconventionally about physics. Many inventors succeed by looking past conventional wisdom to imagine new possibilities.
