The phrase "by rote" typically means to learn or memorize through repetition without necessarily understanding the meaning behind what is being memorized. Some synonyms for "by rote" include: mechanically, automatically, routinely, systematically, habitually, mindlessly, offhandedly, robotically, and unthinkingly. These terms all describe a method of learning that does not involve critical thinking or analysis, but rather relies on repetition to store information in the brain. While learning by rote can be effective in some contexts, it's important to also understand the meaning behind what is being memorized in order to truly master a subject or skill.
