«groyne» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

### In the lessons

In geography lessons on coasts (UK, Ireland, Australia, New Zealand), groynes are a kind of «hard engineering» that stops longshore drift, the way waves move sand along the coast. Beaches with groynes have more sand on one side. Phrases: wooden groynes, coastal defences, longshore drift.

### Examples

### Note

British spelling: groyne. American spelling: groin, which is also the word for the top of the inside leg, so the British spelling avoids a mix-up. Rhymes with «coin». Safety: do not climb on slippery groynes when the tide is coming in.
