Parole essentially means granting the right to enter or remain the US to an applicant who does not technically meet the conditions for the visa or status. It's usually applied on humanitarian grounds or to fill "gaps" in the immigration system [1] where there would be negative consequences.
It's an attempt to soften the harsh consequences that often arise from these counterintuitive rules in a very technical legal space that is almost impossible to legislatively correct.
