protractive

1. (linguistics) Indicating an action or state that is ongoing or sustained.Examples: "One inflected form of the durative verb is made with a long tense hold and without motion; the nuance in meaning is the same as that of the protractive modulation of adjectival predicates and translates as 'to stare at (uninterruptedly)' (figure 12.15b)."; "The protractive, durational, and continuative morphemes are examples of nonpunctual modifications ."; "Fleischmann (1990:22), Sebastian and Slobin (1994: 257-8) also discuss the classivication of so-called aspectual verbs into inchative verbs (e.g. empezar, to start), protractive verbs ( e.g. , quedarse, to remain), cumulative verbs ( e.g., continuar, to continue) and and empletive verbs (e.g. acabar de, to finish).."

2.
