cay

Cay comes from Taíno cayo, a word for a small low island or reef islet in the Caribbean. Spanish explorers adopted it almost immediately after 1492 as cayo. English later borrowed the term as cay, stripping the final vowel but keeping the sea. The geography was too specific to translate neatly.

This is what colonization often did to island words. It kept them because the newcomers lacked a better map term. Taíno gave European empires names for realities they had not previously needed to distinguish. The language of conquest was full of dependence.

Through Spanish navigation and Caribbean charting, cayo spread across the colonial Atlantic. English mariners and mapmakers picked up cay in relation to the Bahamas, Florida, and the wider West Indies. The word stayed coastal and technical. It never wandered far inland.

Modern English uses cay for sandy, low-lying islets, especially in tropical waters. The term appears in geography, tourism, and place names from Key Largo's older cousins to Belizean reefs. It is short, precise, and saline. Some words taste of coral.
