The video tutorial introduces the concept of 'flossy words,' which are words ending with the sounds F, L, or S. It explains that short vowels without letter friends need a double letter at the end for 'tickle power,' while vowels with letter friends only need one letter. Examples like 'shelf,' 'meal,' and 'fans' illustrate when to use single letters. The tutorial emphasizes understanding these rules to improve spelling skills.
