EXPLAIN keyword, does it execute query as well or just "explains" the query?

Question

Does the EXPLAIN keyword in an INSERT or UPDATE statement execute the query, or is it just going to show ('explain') the query for you - newbie to MySQL and couldn't find the question quick enough.

Answer 1

Reference says

The EXPLAIN statement provides information about how MySQL executes statements:

Query is not executed. Some other databases have an 'EXPLAIN ANALYZE' which actually does the explain and does the query. Mysql does not have this feature
