This is the 7256th most frequent Portuguese word.
mam
The word "mam" does not have meaning in Portuguese. It might be a typo or abbreviation.
The word "mamava" refers to the act of nursing or feeding on milk, specifically in the context of infants.
Eu mamava leite materno quando era bebê.
I used to nurse on mother's milk when I was a baby.
Here, "mamou" is used informally to mean drinking, especially for children transitioning from breastfeeding.
Ela mamou no copo pela primeira vez.
She drank from a cup for the first time.
In this instance, "mamava" again relates to feeding on milk, but in the context of animals.
