Key Differences

"Aunty" and "Aunt" both refer to a relative, specifically the sister of a parent or the wife of an uncle. However, "Aunty" is generally seen as a more informal and affectionate term.
In different cultural contexts, "Aunty" might be used more broadly to refer to a woman of the older generation in a community. "Aunt," on the other hand, usually sticks more closely to the biological or legal relationship.
Grammatically, both "Aunty" and "Aunt" function as nouns. They can serve as the subject, object, or complement in a sentence, yet "Aunty" is more colloquial.
In written language, "Aunt" is more commonly used in official or formal documents. "Aunty," conversely, is more often found in personal correspondence or casual writing.
Both "Aunty" and "Aunt" can appear with or without a name following them (e.g., Aunt Jane or Aunty Jane). However, "Aunty" is more likely to be used with a name when speaking to children, to add a layer of warmth.
