IPA: /ˈæntliːər/
KK: /ˈæntliːər/
Relating to or characteristic of an aunt, especially in a more pronounced or intensified way.
She has become even auntlier since she started taking care of her niece.
The word 'auntlier' is derived from 'aunt' (from Middle English 'aunte', meaning a sister of one's parent) and the suffix '-lier' (a comparative suffix indicating more of a quality). Thus, 'auntlier' refers to someone who is more like an aunt or possesses aunt-like qualities.
Think of 'aunt' as a family member and '-lier' suggesting more of that quality — so 'auntlier' means having more aunt-like traits.
