This article examines the verbal morphology of the Old English interlinear gloss to the Durham Collectar,
attributed by almost universal consensus to Aldred of Chester-le-Street, whose earlier gloss to the Lindisfarne Gospels has
recently been the object of scholarly attention (Cole 2014; Fernández Cuesta & Pons-Sanz 2016, Gameson et al. 2017). This article analyses
-s/-th variation in the present indicative and imperative forms in relation to their syntactic context,
in particular subject type and subject-verb adjacency, in order to assess whether the Northern Subject Rule detected by Cole (2014) in Lindisfarne was also operative in Aldred’s later gloss. By means of a
quantitative analysis, we find that the first constraint does not significantly affect -s/-ð
variation in the gloss and that there is insufficient context for the second. Additionally, it is argued that adjacency is a
problematic variable in this text-type. We also demonstrate that there is a higher percentage of second person singular
-st and -ð in the Collectar than in Lindisfarne and discuss the possible influence of
standard West Saxon on the later gloss.
