to cover with cobwebs; to make dusty or neglected-looking.
From 'be-' plus 'cobweb'. The word 'cobweb' itself comes from Middle English 'cop' (meaning spider), so this verb means 'to make covered in spider webs,' indicating age, neglect, or abandonment.
The word 'cobweb' originally meant 'spider web'—'cop' was an old word for spider—so becobwebbed literally means 'covered in spider's handiwork,' a poetic way to describe something forgotten and dusty.
