sobei
"Sobei" is not a standard Portuguese word; it might be a typo or variation.
The term 'sobei' represents a conditional hypothetical statement with the verb 'subir' referring to a potential action of ascending prompted by 'eles'.
Se eles sobei agora, não vão encontrar a reunião iniciada.
If they go up now, they won't find the meeting already started.
The word 'sobei' is the verb 'subir' conjugated in subjunctive, used here to indicate action performed by 'vocês' referring to ascending.
Vocês sobei pela escada para chegar ao terraço.
You go up the stairs to reach the terrace.
This use of 'sobei' in a subjunctive mood reflects the speaker's concern and hope for the careful ascent by 'vocês' based on the verb 'subir'.
