-The `EXPLAIN` statement shows the execution plan for a query without executing it. It is complimented by `EXPLAIN ANALYZE` which will execute the query. If the output of `EXPLAIN` does not match the expected result, consider executing `ANALYZE TABLE` on each table in the query.
+The `EXPLAIN` statement shows the execution plan for a query without executing it. It complements the `EXPLAIN ANALYZE` statement, which executes the query.
