A Scottish or Northern English dialect word for a ravine or small valley, or a person who tends to waterfalls and streams.
From Old Norse and Scottish Gaelic elements, with connections to 'gill' (a ravine or stream). The term evolved in northern British regions where topography featured many such geographical features. Historical documents show it was commonly used to describe landscape workers.
The word 'gillar' reflects how communities name landscape features based on what they interact with daily—Scottish people who lived near rushing water and gorges needed words to describe these places precisely, just as Inuit peoples have many words for snow.
