The video tutorial explains the concept of roots, prefixes, and suffixes in word formation. It uses the word 'reheated' to demonstrate how root words can stand alone and how prefixes and suffixes alter their meanings. The prefix 're' means 'again', and the suffix 'ed' indicates past tense, showing how 'reheated' means 'heated again in the past'. Understanding these components helps in deciphering unfamiliar words.
