This is the 1651st most frequent Portuguese word.
quase
Almost.
Here, 'quase' is used to indicate that an action is nearly completed, but it is not fully done yet.
Quase terminei a tarefa.
I almost finished the task.
In this case, 'quase' describes an approximation associated with a time duration.
Ele chegou quase duas horas atrasado.
He arrived almost two hours late.
'Quase' here modifies the adverb 'sempre' to convey that the occurrence happens frequently but with exceptions.
