* Тітка (Tіtka): This is the most common and general term for "auntie", used for the sister of your parent.
* Тетя (Tetya): This is a more formal and respectful term, also used for the sister of your parent, especially if you are addressing her as a stranger or in a formal setting.
* Цяця (Tsya-tsya): This is a more affectionate and familiar term, used for a close aunt or a maternal figure.
* Тітонька (Tіton'ka): This is a term used for a slightly older woman, similar to "auntie", but not necessarily related. It can also be used as a friendly term for a woman who is like a mother figure to you.
The best way to choose the right word is to consider the age of the person you are addressing, your relationship with them, and the level of formality of the situation.
