Situated at or forming the absolute end; furthest or final in position or sequence.
From Old English 'ende' (end) plus the superlative suffix '-most' (meaning 'most'). This formation parallels 'topmost,' 'uppermost,' and 'foremost.'
'Endmost' is delightfully redundant—it means 'the most end' which is funny because 'end' already means the final point, but languages often stack modifiers for emphasis, like how we say 'very very very.'
