### sense in the lessons

In geography lessons about rivers a weir is a human-made feature that controls water, helps mills and measures flow. Fish ladders help salmon get past weirs. Safety lessons warn that the water below a weir can trap swimmers and boats in a dangerous swirling current, so never swim near one. Phrases: over the weir, a weir pool.

### note

Countable: a weir, weirs. Pronounced like "we're" or "wear" in some accents (UK: WEER). Homophone trap: weir (dam) vs we're (we are); not to be confused with "weird". Safety: weirs look calm but are among the most dangerous places on a river.
