The word "barchane" is a bit tricky to spell as it is derived from a French word "barchan". It is pronounced as "bar-shahn" in IPA phonetic transcription. The spelling seems unusual with the combination of "ch" and "ane", but it actually reflects the sound of the word more accurately. A "barchane" is a crescent-shaped sand dune, often found in deserts, and is an interesting geological formation worth exploring.
