This noun is made up of 'Grund' (land) and 'Besitzer' (owner). Here, 'Grund' means 'Grund und Boden' (land and soil), that is, land. A 'Grundbesitzer' is therefore literally a landowner.
Als großer Grundbesitzer hatte er viel Einfluss in der Region.
As a large landowner, he had a lot of influence in the region.
The component 'Besitzer' (owner) belongs to the word family of 'besitzen' (to own) and 'der Besitz' (property, possession). All these words refer to ownership.
Er besitzt mehrere Grundstücke in der Stadt.
He owns several plots of land in the city.
Typical verbs used with 'Grundbesitzer' (landowner) describe dealing with land ownership. These include, for example, 'Land verpachten' (to lease land), 'Grundstücke verkaufen' (to sell plots of land), or 'Felder bewirtschaften' (to cultivate fields).
Der Grundbesitzer will sein Land nicht verkaufen.
The landowner does not want to sell his land.
owner
'der Besitzer' and 'der Grundbesitzer' both refer to someone who owns something. 'der Besitzer' is the general word for many things: a car, an animal, an apartment, or a plot of land. 'der Grundbesitzer' is much more specific and means someone who owns land or a plot of land. The words can be confused because plots of land can also be possessions. If you are speaking generally about ownership, 'Besitzer' fits. If you mean land and property specifically, 'Grundbesitzer' is more precise.
