explicit premise is incorrectly written and it should be written as "explicit premise" being its meaning:
A premise of the participle praemissus praemissa praemitto praemissum, meaning sent forward, placed in front of the conclusion, since a premise is always a logical proposition ( significant linguistic expression which can be true or false ) that is part of a logical reasoning that there are always at least two premises and a conclusion that it necessarily follows from the premises, if the reasoning is correct. This premise is explicit if it is referred to or expressed openly and manifestly and not only néfissa, i.e., implied. Explicit is the feminine singular of one of the forms of the past participle of the Latin verb explain explain explain explicavi explicatum which means deploying, developing, refer verbally, explain
