Very recently; in the immediate past.
"The newly arrived guests are already unpacking their bags in the hallway."
In plain English: Newly means something just happened very recently.
"She is newly married and very happy."
Usage: Use newly as an adverb to mean very recently or just now, typically placing it before the main verb or after auxiliary verbs like have and did. Avoid confusing it with new, which describes something that has never been used before rather than when an action occurred.
Newly comes from Middle English and traces back to Old English, where it originally meant "in a new condition." The word entered modern usage by combining the adjective new with the suffix -ly, following a pattern similar to related terms in Dutch and German.
