To disseminate means to spread information widely, like scattering seeds across a field. When scientists disseminate their research findings, they publish papers and give presentations so other researchers around the world can learn from their work. When a school disseminates news about an upcoming event, they might send emails, post flyers, and make announcements so everyone hears about it.

A rumor might disseminate quickly through a cafeteria as students whisper it to each other. A library disseminates books by lending them to readers throughout the community. Health organizations disseminate important information about staying healthy through posters, websites, and community programs.

Disseminate suggests a deliberate, organized effort to share information widely rather than just telling one or two people. When you disseminate something, you're making sure it reaches as many people as possible, the way a dandelion disseminates its seeds on the wind, sending them far and wide.
