The word is made up of 'das Taxi' (taxi) and 'der Fahrer' (driver). As with many German compounds, the last word ('Fahrer') determines the article 'der'.

The structure 'Transportmittel + Fahrer' (means of transport + driver) is a very common pattern for forming job titles in German. Other examples are 'Busfahrer' (bus driver), 'LKW-Fahrer' (truck driver), or 'Zugfahrer' (train driver).

In everyday life, the word is often used in sentences that describe typical actions. These include 'einen Taxifahrer rufen' (to call a taxi driver), 'dem Taxifahrer das Ziel nennen' (to tell the taxi driver the destination), or 'dem Taxifahrer ein Trinkgeld geben' (to give the taxi driver a tip).

'der Fahrer' and 'der Taxifahrer' can both mean a person who operates a vehicle. 'Der Fahrer' is general and can fit many types of vehicles. 'Der Taxifahrer' is more specific: he drives a taxi professionally and takes passengers to their destination for payment. Learners may confuse the words because a taxi driver is, of course, also a driver. When talking about the profession or a taxi ride, 'Taxifahrer' is more natural. In other situations, 'Fahrer' is often enough.

Because of the rain, we call a taxi driver.
Nach der Arbeit wartet der Fahrer kurz vor dem Büro.
