Difficulties in agreement (concord)

 

In some cases, difficulties arise in the agreement between the finite verb and the subject. This occurs mainly when the subject consists of more than one words. Some of these difficulties are presented below:

 

 

Multiple subjects, where both the 1st and the 2nd person are present

 

subject connected with person of the finite verb form
1. person + 2. person (singular or plural) und, sowohl...als auch, sowie, weder...noch 1. person plural
