LSC uses inflectional morphology in some type of verbs in order to express agreement. Namely, agreement and spatial verbs make use of space in order to mark the subject and the object of the sentence (agreement verbs), or the location where the event takes place or the source and goal locations between which movement happens (spatial verbs). Also, a subset of plain verbs, the ones that are not body anchored, can show agreement with one of their arguments. However, inflectional morphology is not only used for the expression of agreement. Verbal roots also use inflectional morphology in order to express aspect. This chapter describes different morphological strategies that LSC uses in order to express agreement, tense, aspect, modality and negation.
