What are the ADUSO conjunctions in German

By the end of this lesson, you will be able to correctly use the ADUSO conjunctions to connect various clauses and express your thoughts clearly.

In this lesson, we will explore the conjunctions represented by the acronym ADUSO. These conjunctions link two or more clauses, helping clarify the thought process in sentences. The term ADUSO stands for five essential conjunctions in German:

A: aber
D: denn
U: und
S: sondern
O: oder

Each of these conjunctions has a specific function.

1. Meaning and Use of the ADUSO Conjunctions

Here are the functions and examples for each conjunction:

Conjunction	Function	Example	Translation
aber	Connects contrasting clauses	I enjoy chocolate, but I rarely eat it.	I like chocolate, but I rarely eat it.
denn	Connects cause and effect clauses	I am tired because I did not sleep.	I am tired, because I did not sleep.
und	Connects supplementary thoughts	He plays football and he enjoys swimming.	He plays football and he likes swimming.
sondern	Connects contradictory clauses	She doesn’t like coffee, but she drinks tea.	She doesn’t like coffee, but she drinks tea.
oder	Connects choices	Are you going to the cinema or staying home?	Are you going to the movies or staying home?

2. Applying the ADUSO Conjunctions in Sentences

When using ADUSO conjunctions, the sentence structure remains constant. The subject (S) comes first, followed by the verb (V) and additional sentence parts.

Example:

I like playing chess, but I don’t have time.
(I like playing chess, but I don’t have time.)

Here, the conjunction “but” shows that the second statement contrasts with the first.
