sągów
"Sągów" is not a standard Polish word. It may be a form or misspelling; additional context is needed.
The word 'sągów' is the plural genitive form of 'sąg', used here to describe multiple stacks (or piles) of wood.
Na podwórku koło domu stoi kilka sągów drewna.
In the yard near the house, there are several piles of wood.
The word 'sągi' here is used in the accusative plural form to directly refer to the stacks of wood prepared for chopping.
Przygotowałem wszystkie sągi do porąbania na zimę.
I prepared all stacks of wood to be chopped for winter.
In this sentence, 'sągów' appears again in the plural genitive, describing ownership or possession of the remnants (of the stacks of wood) found after the fire.
