haystack

The word 'haystack' is a transparent compound formed from two Old English and Old Norse elements, each retaining its core meaning. 'Hay', from the Old English 'hieg', refers to the dried grass used as animal fodder. 'Stack', borrowed from the Old Norse 'stakkr', specifically meant a pile of hay or corn. The compound literally means "a pile of hay," and its formation follows a simple, descriptive pattern common in English, where two concrete nouns combine to name a familiar agricultural object. Its logic is entirely literal, with no semantic shift from the original parts.
