'ascot' (the neckwear) takes its name from the place 'Ascot' in Berkshire, England; the fashion for the tie is associated with wearing such neckwear to events at Ascot Racecourse.

'ascot' (the tie) was named after the place-name 'Ascot' and its famous race meeting; the place-name 'Ascot' itself comes from Old English elements, essentially 'east' + 'cot' (cottage or shelter).

Originally a place-name, the term later came to denote the particular style of neckwear associated with attendees at Ascot; over time it generalized to mean that style of decorative neck scarf or tie.
