🔹 Denominal Nouns Formed with -ía

The suffix -ía forms feminine nouns from nominal bases. With nouns referring to people, professions, offices, ranks, or social positions, it commonly expresses:

• office, position, rank, or status: alcalde → alcaldía, secretario → secretaría;
• place or institution where that office operates: comisario → comisaría, notario → notaría;
• profession or professional activity: abogado → abogacía, ingeniero → ingeniería;
• condition or membership: ciudadano → ciudadanía;
• collective groups: feligrés → feligresía, marinero → marinería.

A particularly important characteristic is that the same derivative may designate both the position/institution and the place: concejalía can mean the office of a councillor or the department where that activity is carried out.

The nouns are ordered approximately by contemporary frequency and general usefulness.
