Scruffiest → It is formed from "scruffy" (from the dialectal English "scruff", meaning the nape of the neck or a dirty, unkempt appearance) and the suffix "-est" (meaning most). The word "scruffiest" means having the most unkempt or dirty appearance.
Think of someone who looks the most 'unkempt' or 'dirty' — 'scruffy' describes that look, and '-est' indicates the highest degree.
