The Spanish word 'bochorno' comes from the Latin word 'vulturnus', which referred to a southeast wind. 'Vulturnus' itself was derived from 'vultur', the name of a mountain. Over time, as the word evolved from Latin to Spanish, both its pronunciation and meaning shifted. The 'v' changed to 'b' (a common sound change in Spanish), and the '-ult-' cluster simplified to '-och-'. Today, 'bochorno' refers to both a hot, suffocating wind and, metaphorically, to a feeling of embarrassment or shame – perhaps drawing a connection between the discomfort of hot weather and the physical discomfort of feeling embarrassed.

While 'bochorno' has a unique development in Spanish, it's worth noting that the word 'bochornoso' (meaning 'embarrassing' or 'shameful') is derived from it and is commonly used in modern Spanish.

While there aren't any common English words directly related to 'bochorno', English speakers might find it interesting that the Latin root 'vultur-' is the same root that gave us the word 'vulture'. The mountain name 'Vultur' might have been associated with these birds of prey, though the semantic connection to the wind term and eventually to the Spanish word for hot wind and embarrassment followed a different path.
