means A regularly distributed publication, typically delivered by email or post, that updates a specific audience on news, ideas, or products.

from A transparent compound of "news" and "letter," both old English-friendly words. "News" is simply "new" pluralized into "new things" (paralleling Middle Dutch and German formations), while "letter" descends from Latin "littera," a written character or epistle. The pairing is modern: it named the printed bulletins that organizations and societies mailed to members, long before any inbox existed to dread them.
