This is the 1528th most frequent Polish word.
areszcie
"In custody" or "under arrest."
'Areszcie' is used in its literal sense of a correctional facility or state of confinement.
W areszcie czas mija inaczej, powoli.
In custody, time passes differently, slowly.
Here, 'areszcie' refers to 'custody' as a legal situation.

We finally reached the place and were in custody.
'Areszcie' here metaphorically represents being absorbed or held in a state, specifically of happiness.
