Etymology
The compound adjective 'half-filled' is a transparent combination of two native English elements. 'Half' originates from the Proto-Germanic 'halbaz', meaning 'side' or 'part', which evolved into the Old English 'healf', denoting one of two equal parts. 'Filled' derives from the Old English verb 'fyllan', meaning 'to make full', from the Proto-Germanic 'fullijaną'. The logical construction is entirely literal: the state of being made full to only one part (or side) of capacity. This straightforward compounding reflects a common Germanic pattern for creating descriptive states, where a quantifier modifies a past participle to specify a degree of completion.
