What part of speech is “mother”

a mother is a female parent and the female role in the creation and upbringing of a child. In a familial context, her role is to provide care and protection for her offspring. Mothers traditionally take on the maternal role of nurturing and providing for their children and can also be seen as the primary caregiver in a family.

1. My mother always knows how to make me feel better.

2. She was a mother to all of the children on the playground.

3. I heard my uncle address his wife as 'mother' in a kind way.

when referring to a mother figure in a child’s life, like a step-mother or grandmother, the respectful term 'mother' should be used. Also, avoid using 'mama' when referring to a mother in a formal setting.
