Antonyms

Usage Note

Common Mistakes

We sailed across the bay.
'bay' already implies a part of the sea, so 'ocean bay' is redundant.

Usage Note

Almost always appears with a modifier that names the purpose: parking bay, loading bay, service bay, sick bay, drive bay, cargo bay. The bare word 'bay' rarely conveys this sense without context.

Usage Note

In modern cooking, speakers usually say 'bay leaf' or 'bay leaves'; the bare word 'bay' for the leaf is more literary or compressed (recipe shorthand). The tree is also called 'bay laurel' or 'sweet bay' in horticulture.

Common Mistakes

Remove the bay leaf before serving.
bay leaves flavour the dish but are too tough to eat.

Common Mistakes

Synonym discussion

Sense: noun/1

All five words name water bodies that reach into the land, but they differ in size, shape, and use. A 'bay' is moderately sized — bigger than a cove, smaller than a gulf — with a wide, gentle curve of shore. A 'gulf' is much larger and often opens directly to an ocean (the Gulf of Mexico, the Persian Gulf). A 'cove' is small, intimate, and well sheltered — the kind of spot a single boat might anchor in for the night. An 'inlet' emphasises a narrow opening rather than a curve, often long and finger-like. A 'harbor' adds a human element: it's a sheltered area, natural or built, where ships can dock safely. So sailors might cross the gulf, sail into the bay, drop anchor in a quiet cove, or tie up at the harbor — each word picks a different feature of the same kind of place.

Etymology

LatinOld FrenchMiddle EnglishModern English

The headword 'bay' covers several meanings that came into English by separate routes and only happen to share spelling. The geographic 'bay' (a curve of coast) reached English through Old French 'baie', tracing back to Late Latin 'baia'. The 'bay' for a building section comes from Old French 'baee', meaning an opening, from a verb meaning 'to gape'. The plant 'bay' (the laurel) comes from Old French 'baie' meaning 'berry', from Latin 'baca'. The horse-colour 'bay' comes from Old French 'bai', from Latin 'badius', meaning reddish-brown. The hunting-dog 'bay' (a long howl) comes from Old French 'abaiier', meaning to bark. So four distinct sources, all by chance settling on the same three letters in modern English.
