Feitinho is the diminutive of feito (made). It translates to "made just right" or "perfectly made," adding a tender and affectionate nuance to the word.
In the song, the lyric "Foi feitinho pra dar" means "It was perfectly made to give." This phrase beautifully conveys the idea that love is inherently designed for sharing and giving, making it a charming and memorable word choice.
"Samba De Verão" is Caetano Veloso's recording of the bossa nova standard better known abroad as "Summer Samba (So Nice)," written by Marcos Valle. It opens with a startled compliment, "Você viu só que amor" ["You saw what love looks like"], for a girl who is gone before he can hold onto her: "E passou, nem parou" ["And it passed, didn't even stop"]. He spends the rest of the first half promising himself he'll act differently if she comes back — "Se voltar vou atrás" ["If it comes back I'll chase it"] — because the feeling itself is as simple as the weather: "Olha, é como o verão" ["Look, it's like summer"].
The second half circles back to the same shape with a new girl in view, "Para ver a menina que vem" ["To watch the girl who comes"], and ends on a plea that goes unanswered, "Peço, mas você não vem" ["I beg, but you don't come"]. Veloso keeps Valle's light, sun-drenched melody but leaves the story open — the song is about wanting love to return, not about getting it back.
