perfume

perfume: [16] The -fume of perfume is the same word as English fumes, but whereas fumes has gone downhill semantically, perfume has remained in the realms of pleasant odours. It comes from French parfum, a derivative of the verb parfumer. This was borrowed from early Italian parfumare, a compound formed from the prefix par- ‘through’ and fumare ‘smoke’, which denoted a ‘pervading by smoke’. When it first arrived in English, the semantic element ‘burning’ was still present, and perfume denoted the ‘fumes produced by burning a substance, such as incense’, but this gradually dropped out in favour of the more general ‘pleasant smell’.
