'England-hostile' originates from Modern English, specifically the words 'England' and 'hostile', where 'England' refers to the country name derived from Old English 'Englaland' and 'hostile' comes from Latin 'hostilis' meaning 'of an enemy'.

'England' changed from Old English 'Englaland' (literally 'land of the Angles') into the modern name 'England'; 'hostilis' passed into Old French and Middle English as forms like 'hostil' and eventually became modern English 'hostile'. The compound 'England-hostile' is a straightforward modern English compound formed by joining the country name and the adjective.

Initially, 'Englaland' identified the land of the Angles and 'hostilis' meant 'of an enemy'; over time they evolved into the modern geographical name 'England' and the adjective 'hostile' meaning 'unfriendly'—combined to mean 'unfriendly toward England'.
