Expert writing Tips
Best practice
In academic and scientific contexts, this phrase is most effective when used in the negative (e.g., "not yet understood completely") to accurately describe the limitations of current research.
Common error
Do not combine "understood completely" with other absolute adverbs such as in "totally understood completely". Because "completely" already implies a 100% state, adding more adverbs is redundant and clutter your prose.
