A more thorough explanation:

A noverca is a woman who marries a man who has children from a previous marriage and becomes their stepmother.

• After his father remarried, John's noverca helped him with his homework and took him to soccer practice.
• The noverca was kind to her stepchildren and treated them as if they were her own.

These examples show how a noverca is a stepmother who takes care of her husband's children from a previous marriage. They also show that a noverca can be loving and caring towards her stepchildren.
