What does “abolengo” mean in Spanish?

Abolengo is inherited lineage, usually the distinguished kind: de abolengo marks an old, well-bred family with a pedigree to show. It is built on abuelo (“grandfather”), the line that comes down from your forebears. A family de rancio abolengo is one of long-standing, slightly faded nobility; the word carries a whiff of old money and inherited status that plain familia or origen never does.

Near-synonyms are alcurnia, linaje, and prosapia (all “noble stock”). Watch the slip in the clip — abuelengo isn’t a word; the form is abolengo, even though the abuelo connection is exactly what your ear expects. It is a register-rich term: literary, a little grand, perfect when a character is putting on airs about where they come from.
