Answer:
Affirmative
Step-by-step explanation:
The original word in Latin positivus (settle by agreement, positive) means formally stated, definite. It's affirmative (affirmativus: making firm), refering to terms for a sentence, clause, verb, or other expression that is not negative (She is studying ) as opposed to She is not studying ). It is also the base form, for example, with adjectives (big : positive) as opposed to the comparative or superlative forms (bigger; biggest ).
