Koichi gave an oral report of Tofugu's annual report for the workers.
I’m thinking about the funniest way to inform my boyfriend that I’m pregnant so that he won’t run away from me.
News that you announce becomes a report. When someone announces news on a topic, they are giving you a report on the information.
報告 is a report given by someone after they've done some investigation or research into the topic. It can be used for class presentations on a topic or a report given to your boss. This differs from 報道, which is a report released by news organizations.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
