mile-and-a-half

The term is a straightforward descriptive compound, formed in Modern English by combining standard lexical items to specify a precise measurement. Its logic is purely arithmetic and literal, denoting a distance that is the sum of one mile and an additional half-mile. Unlike words with fused classical roots, its meaning is transparently derived from the modern meanings of its constituent words: 'mile' (the unit), 'and' (signifying addition), and 'a half' (the fractional amount). This construction exemplifies how English creates precise, compound numerical descriptors for common use.

Structure: mile (unit of distance) + and (conjunction) + a (article) + half (fraction) This is a fixed compound noun phrase. 'Mile' originates from Old English 'mīl', from Latin 'mīlia (passuum)', meaning 'thousands (of paces)'. 'And' is from Old English 'and', 'ond', a conjunction. 'A' is the indefinite article from Old English 'ān' (one). 'Half' is from Old English 'healf', meaning 'side, part'.
