E arm of a single large moat? (1)
There is no surface evidence that these features ever formed a single unit. The E feature is a deep open ditch with rising ground to the W, the sides are steep and there is evidence of quarrying at the N end. Not a moat, the situation is not suitable and there is no evidence of other arms. (2)
If connected - and they (including L 9410) probably are - they would make 2 sides of a roughly rectangular enclosure, with church perhaps at centre, as it is roughly equidistant from the 2 "moats". An early village boundary earthwork ? (3)
See L 9410 for western "arm", L 7677 for nearby linear hollow.
