Formal:
* Magsaya ka! (This is the most direct translation and works in most situations.)
Informal:
* Enjoy! (This is often used in English, especially when talking to someone you know well.)
* Masaya ka! (This is similar to "magsaya ka" but slightly more informal.)
* Enjoy ang araw mo! (This means "Enjoy your day!" and is a more casual way to say "have fun.")
Specific Situations:
* Mag-enjoy ka sa party! (Enjoy the party!)
* Magsaya ka sa bakasyon! (Have fun on your vacation!)
* Mag-enjoy ka sa paglalaro! (Have fun playing!)
Tip: You can also use the verb "magsaya" with a preposition like "sa" to indicate the activity you want someone to enjoy. For example, "Magsaya ka sa paglalakad" means "Have fun walking".
No matter which phrase you choose, the important thing is to say it with a smile and a genuine wish for the person to have a good time!
