This is the 4803rd most frequent Spanish word.
crecía
"Crecía" means "was growing" or "used to grow."
'Crecía' is used in the past imperfect tense, indicating a continuous or habitual action in the past, describing the childhood environment of the subject.
Cuando era joven, crecía junto a un río hermoso.
When I was young, I grew up by a beautiful river.
'Crecía' again in the past imperfect tense reflects the action of the tree growing as an ongoing process in the past.
El árbol crecía lento pero constante en el jardín.
The tree grew slowly but steadily in the garden.
Here, 'crecía' is used to show an abstract concept such as confidence experiencing gradual growth over a period of time in the past.
