Relating to or characteristic of Guitton, a place or person, or relating to a specific historical or cultural group.
From Guitton (a place name or surname) + '-ian' (meaning of or relating to). The '-ian' suffix comes from Latin '-ianus' and is used to form adjectives and nouns of origin or relationship.
This word is very rare in modern English, which tells us something important: most place-based adjectives (-ian words) only survive if the place becomes historically significant enough that people keep using them — most disappear from dictionaries when nobody talks about that place anymore.
