From Proto-Slavic *gora, meaning "mountain, forest, wooded upland," shared across all Slavic languages (Polish góra, Czech hora, Serbian гора). Cognate with Lithuanian girià ("forest") and possibly with Proto-Indo-European *gʷorH- ("mountain, height"). The word's dual sense of "mountain" and "forest" in older Slavic reflects how wooded highlands were perceived as a single concept.

Mountains hold a special place in Russian cultural imagination despite Russia's predominantly flat terrain. The Caucasus range in the south inspired Romantic-era poets — Pushkin and Lermontov both wrote famous works set there. The idiom "горе́ть как гора́" (to burn like a mountain) reflects the word's figurative weight. The phrase "гора́ с плеч" (a mountain off one's shoulders) is a very common idiom meaning a huge relief, equivalent to English "a weight lifted." Note: гора́ and го́ре (grief, woe) are false friends in appearance but distinct words — mind your stress!
