Arrestingly → It is formed from "arrest" (from Old French *arrest*, meaning to stop or seize) and the suffix "-ingly" (indicating a manner of doing something). The word "arrestingly" means in a manner that captures attention or stops one in their tracks.
Think of something that 'stops' or 'captures' your attention ('arrest') and how it does so 'in a manner' ('-ingly'). This helps you remember that 'arrestingly' describes something that grabs your focus.
