glacier

Glacier is masculine in French. It is a noun meaning "ice cream" or "glacier" (the geological formation). The word derives from Old French "glaciere" (feminine), which came from Latin "glacies" (ice, feminine). However, the modern French "glacier" is masculine, likely due to reanalysis and analogy with the productive masculine "-er" suffix in French, which is commonly used for agent nouns and other masculine formations. This represents a gender shift from the original feminine Latin root.
