Signally → It is formed from "signal" (from Latin "signalis", meaning of or pertaining to a sign) and the suffix "-ly" (meaning in a manner). The word "signally" means in a manner that is significant or noteworthy, often used to indicate something that stands out or is important.
Think of something being done in a way that is 'noteworthy' or 'significant' — 'signal' relates to signs, and '-ly' indicates the manner of doing it.
