Tips
Use yo for new information
Use this particle when you are telling someone something they don't know yet. It acts like an 'I'm telling you' marker.
Be careful with authority
Using 'yo' with a plain verb form can sound bossy or condescending to superiors. Always use 'desu yo' in formal settings.
