In German, the compound word 'Clausius' can be broken down to two parts: 'Claus' and 'ius'. The first part 'Claus' is thought to stem from a Germanic masculine personal name, which in turn is derived from the Latin word 'Claudius'.

For example, in Austria, there are communities where the name is relatively prominent, including a number of villages in the states of Lower and Upper Austria.
