1569: WLAN in German Apr 1, 2019
In English 'WIFI', is a common term but it ultimately doesn't stand for anything except 'wireless', but even so the same word is used in a plethora of languages from Swedish to Korean. In German however, the equivalent term is 'WLAN', which is an acronym, but not a German one. Instead, it comes from 'wireless local area network', which is still English, but it just so happens that while German term is a loan word, it is the less common one, both within English and across languages. In German, WLAN would translate to 'kabellose Netzverbindung', but that doesn't abbreviate as well apparently.
