2.4.1.1. Null subjects
In DGS, null subjects occur with plain, spatial and agreement verbs [Lexicon 3.2]. Plain verbs [Lexicon 3.2.1] are not modified for agreement purpose; thus, the referent of the omitted subject argument must be retrievable from context as demonstrated below.
ix1 cake bake / unfortunately burn
โI baked a cake. Unfortunately, (the cake) burnt.โ
With body-anchored plain verbs, omitted subject arguments typically refer to a first-person referent.
like team together
โ(I) prefer team sports.โ
(based on Oomen, 2020: 139)
Agreement verbs [Lexicon 3.2.2] change path movement and/or finger orientation to mark agreement with their subject and object arguments. Consequently, a modified movement or orientation clearly indicates the subject referent so all kinds of subject arguments can be dropped. Subject omission with backward agreement verbs is rare in DGS.
poss1 grandmother3b 3ahelp3b
โ(My mother/she) helps my grandmother.โ
Subject arguments are also omitted with spatial verbs [Lexicon 3.2.3] either with directional spatial verbs as in (a) or with local spatial verbs as in (b).

โThen, (we) went to the office.โ
b. garden sit
