Reading the scores
The score ranks each pairing with Thiago using our editorial rules for shared style, popularity bands, rhyme, endings and initials.

Common questions
What names go well with Thiago for a sibling?
For a brother: Luca, Hudson, Asher, Owen.
For a sister: Lainey, Gianna, Layla, Nova. All of them keep Thiago's general feel but start and end on their own sounds, so the two names never blur together.
Should a sibling name match Thiago?
Only loosely. A brother or sister name should sound like it was chosen by the same parents as Thiago, not like half of a pair. That means a shared era or style — Thiago reads as international and modern, so lean that way — but a different starting sound and ending. Every name on this page shares at least one style label with Thiago. Names that rhyme with Thiago or also start with "T" get fewer points here.
Should a sibling of Thiago have a name from the same language?
It is a small plus, not a rule. Another Portuguese name (like Thiago) gets a small scoring bonus because shared roots read as deliberate, but a strong style match with Thiago matters more either way.
What decides the score for each sibling name?
Each name is checked against Thiago: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Thiago, sharing its "T" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
