Nyla

Oma is a feminine name with Germanic origins, literally meaning 'grandmother' in German and Dutch. The name carries warm associations of maternal wisdom and familial nurturing. While primarily known as a term of endearment for grandmothers in German-speaking countries, Oma has occasionally been used as a given name in the United States, particularly in communities with German heritage. The name peaked in limited popularity in the early 1900s but has since become quite rare as a first name. Oma also appears in Japanese, meaning 'horse,' and in some African languages with various meanings. The name's brevity and soft sounds give it a gentle quality, though its strong association with grandmotherhood in German culture may influence how the name is perceived.

Pema is related to the more familiar Hindu name Padma and means lotus flower. This delightful name was given to only 14 girls in the USA last year, so it's guaranteed to be a unique choice. Pema is probably most familiar to Westerners through Buddhist nun Pema Chodron and through Jetsun Pema, the Dalai Lama's sister. Note: Pema rhymes with Emma.

More popularly used for girls, this peppy word name has been worn by football player Pepper Johnson (born Thomas and given the childhood nickname for sprinkling pepper on his cereal) and appears in the musical Mamma Mia!. Yet to make waves for boys, it was given to five boys in a recent year. 
 
Associated with the drink, Dr Pepper and occasionally Peppa Pig, it's also related to the vegetable (or fruit) and spice, giving it a wordy, nature-y vibe too. There's also the musical link to The Beatle's album, Sgt. Pepper's Lonely Hearts Club might appeal to some. 

Pepper might be a fun nickname for Joseph, Philip, Peter, Peregrine, or Percival.
