gate: Of the two English words gate, only one survives in general use. Gate ‘doorlike structure’ [OE] comes from a prehistoric Germanic *gatam, whose other descendants, including Dutch gat ‘hole, opening’, suggest that it originally denoted an ‘opening in a wall’ rather than the ‘structure used to close such an opening’. Irish has borrowed it as geata.

The other gate ‘way, path’ [13] now survives only in street-names, particularly in the North of England (for instance, York’s Micklegate and Coppergate); its other main meaning, ‘way of walking’, has been partitioned off since the 18th century in the spelling gait. It was borrowed from Old Norse gata ‘path, passage’, which comes ultimately from prehistoric Germanic *gatwōn.
