Happy and Happiness are the kind of old-fashioned Virtue names most contemporary Anglophones would consider unusable, though there are a number of names with the same meaning in other languages. Here are some of them. (For the sake of brevity, I’m not including all the Slavic names starting with Rad. All these Slavic names formed from the same roots merit their own future posts.)
Dilshad means “happy heart” and “cheerful” in Persian.
Huan means “pleased, happy” in Chinese.
Jyrgal is Kyrgyz.
Makena means “happy one” in Kikuyu, a Bantu language spoken in Kenya, Uganda, and Tanzania.
Phúc is Vietnamese, though I’d obviously caution against using this in an Anglophone country!
Simcha is Hebrew.
Xinyi means “joyous, happy, delighted” in Chinese, and may also be composed of characters meaning “heart, soul, mind” and “harmony, joy.”
Yuki is Japanese, though it may also mean “snow.” The meanings of East Asian names can be so complicated!
Zorion is Basque.
Anand is Sanskrit.
Asher is Hebrew. Osher is a Yiddish variation, though the spelling makes me cringe. There’s a reason Sephardic and not Ashkenazic pronunciation was chosen for the resurrection of the Hebrew language in the modern era!
Charalampos means “to shine from happiness” in Greek.
Fortunato means “fortunate, happy, blessed” in Spanish, Italian, and Portuguese.
Gil is Hebrew.
Hani is Arabic.
Harsha, Harshad, and Harshal are Sanskrit.
Kouki is a Japanese name which may be derived from Kanji meaning “happiness” and “hope.”
Macario is a Spanish name derived from the Latin Macarius, which is in turn derived from the Greek Makarios. It ultimately comes from the Greek root makar (happy).
Meriwether means “happy weather” in Middle English.
Milorad is a Serbian and Croatian name composed of the elements milu (dear, gracious) and rad (happy, willing).
Na’im means “happy, tranquil, at ease” in Arabic.
Nobuyuki is a Japanese name which may be derived from the elements “trust” and “happiness.”
Obrad is a Serbian name possibly meaning “to make happy.”
Olukayode means “God brings happiness” in Yoruba.
Onni is Finnish.
Parviz means “happy, fortunate” in Persian.
Sa’id means “lucky, happy” in Arabic.
Selig, or Zelig, means “happy, blessed” in Yiddish.
Shad is Arabic.
Szczȩsny means “successful, happy, lucky” in Polish, and is a vernacular form of Feliks. It’s not very common as a forename in modern Poland, but it is used sometimes.
Taalay means “happy, lucky” in Kyrgyz.
Alaia means “happy, joyful” in Basque.
Bahija is Arabic.
Fariha is Arabic.
Gioconda is an Italian name derived from the Latin Lucunda, which means “happy, delightful, pleasant.”
Heilwig means “happy war” or “healthy war” in Germanic, though it’s not a name I could see working in the modern era. It’s also rather interesting to note how many Germanic names contain elements like “war,” “battle,” and “helmet,” while so many Slavic names contain the elements “peace,” “love,” and “happy.”
Mehetabel, or Mehetavel, means “God makes happy” in Hebrew.
Nandita is Sanskrit.
Radana is Czech and Slovenian.
