Of, relating to, or characteristic of finches; pertaining to the finch family.
Derived from Latin 'Fringilla' (finch) combined with the suffix '-ine' (meaning 'of, relating to, or belonging to'), similar to how 'feline' relates to 'Felis' (cat) or 'canine' relates to 'Canis' (dog).
Notice how '-ine' is used for finches while '-id' becomes 'fringillid' for an individual bird—English and scientific Latin have many ways to express relationships, and switching between them shows how biology thinks at different organizational levels.
