mountain: [13] Latin mōns ‘mountain’ could well go back ultimately to a variant of the base *min- ‘jut’ which produced English eminent, imminent, menace, and prominent. English acquired it originally direct from Latin as a noun, mount [OE], which is now used only in the names of mountains. The verb mount followed in the 14th century, via Old French munter.

Latin mōns had a derived adjective montānus ‘mountainous’, which was adapted in Vulgar Latin to the noun *montānea ‘mountainous area’. This made its way into Old French as montaigne, by which time it meant simply ‘mountain’ – whence English mountain. Amount [13] comes ultimately from the Latin phrase ad montem ‘to the mountain’, hence ‘upwards’; and paramount [16] in turn derives from an Old French phrase par amont ‘by above’, hence ‘superior’.
