What does birr mean?
Birr is the official currency of Ethiopia, subdivided into 100 santim and issued by the National Bank of Ethiopia. It appears most often in financial reporting, travel writing, and everyday commerce within Ethiopia, as in prices quoted in birr or exchange rates against major currencies. The word also survives in an entirely separate, much older sense found in Scottish and Northern English dialect, where it denotes a whirring or rushing sound and, by extension, vigorous energy or momentum — a wheel turning 'with a good birr'. This dialectal sense is now largely literary or regional. Because both senses are nouns pronounced identically, context alone distinguishes them: money in modern usage, kinetic vigour in historical or dialectal writing. The word is short, distinctive, and useful precisely because its two meanings rarely collide.
The basic monetary unit of Ethiopia, equal to 100 santim.
"She paid three hundred birr for the woven basket at the Mercato."
Standard international usage; plural form is typically unchanged ('birr') in careful financial writing.
Scottish and Northern English dialect: a whirring or rushing sound or motion; energetic force or impetus.
"The loom started up with a brisk birr that filled the cottage."
Now rare outside regional and literary contexts.
In financial usage the plural is usually invariant — amounts are written as 'ten birr' or '500 birr', following the practice for many currency names.
"The fare came to sixty birr."
Ethiopia's money is called the birr — and centuries before that, the same little word meant the whirring 'oomph' behind a spinning wheel.

Etymology of birr
The currency sense comes from Amharic, the principal language of Ethiopia, where the word has long denoted silver or money; it became the official name of Ethiopia's monetary unit when the Ethiopian dollar was renamed in the mid-1970s. The dialectal sense of 'birr' meaning a whirring sound or energetic impulse arose independently in Scots and Northern English, imitative of the sound itself. The two words are etymologically unrelated homonyms sharing one spelling and pronunciation.
How birr is actually used
The currency sense is standard international usage and appears mainly in financial and travel contexts. The dialectal sense ('whirring force, vigour') is now rare and largely confined to literary or regional Scottish/Northern English writing; it is often encountered in older literature rather than everyday speech.
