What does the root word cogn- mean?

In my role as an ASVAB tutor, I remind my students There are a number of words with the Latin root cogn-.  Examples include the following words: cognition, recognize, incognito, cognizant, precognition, and cognitive.  I wrote a book entitled The ASVAB Tutor’s Word Knowledge and Paragraph Comprehension Study Guide.  This book consists of over 500 ASVAB vocabulary words.  I also included charts of prefixes, root words, and suffixes to help develop my students’ vocabulary levels.  The Latin root word cogn- is one of the roots I included in my book. Do you know what cogn- means?  I will share the answer and explanation tomorrow
