bulletin
📰 boletín = bolet- (bulla, sealed note) + -ín (small): a small official note
Boletín comes from Italian bolletino, a diminutive of bolla, meaning a seal or official document. So it is literally a little official paper. The -ín ending marks something small, like a short notice sent out regularly.
