What this article means

Legitimate and legitimated children principally use the surname of the father. Legitimation is the process by which a child born outside marriage acquires the status of a legitimate child when the parents later marry.

The word principally signals a default rather than an exclusive command — it establishes the father’s surname as the ordinary rule for legitimate and legitimated children without itself listing every circumstance in which a different result might follow. The article groups legitimate children, who are born to parents validly married to each other, together with legitimated children, whose status arises only after their parents’ subsequent marriage cures what would otherwise have been an illegitimate birth.
