A more thorough explanation:

Amita is a term used in civil law to refer to the sister of one's father, or an aunt on the father's side.

• My dad's sister is my amita.
• When I visited my amita, she told me stories about my dad when he was young.

These examples show how amita is used to refer to a person's aunt on their father's side. The first example states that the speaker's dad's sister is their amita, while the second example shows a visit to an amita and the relationship they have with the speaker's father.
