* גליקליך (gliklikh): This is the most common and general way to say "happy." It translates literally to "lucky" or "fortunate," but it's often used to express happiness.
* פריילעך (freylekh): This means "joyful" or "cheerful" and conveys a sense of lighthearted happiness.
* צופרידן (tsufridn): This means "satisfied" or "content" and is used when someone is happy with something specific.
* גוט (gut): This means "good" and can also be used to express happiness, particularly in greetings like "Gut Yom Tov!" (Happy Holiday!) or "Gut Shabbos!" (Happy Sabbath!)
It's important to note that the best way to say "happy" in Yiddish depends on the situation. For example, you wouldn't say "gliklikh" when you're congratulating someone on their wedding. In this case, you might say "mazel tov!" (Congratulations!) instead.
