What is the most common misspelling

The two most common mistakes in German spelling

The two most common mistakes in German spelling:

1. Incorrect spelling "that / that"
A common mistake made by adults when it comes to spelling is the rule “that / that”.
The conjunction is written with "ss" when it connects the main and subordinate clauses.
As a donkey bridge you can remember:

The conjunction is written with “ss” if the “that” CANNOT be replaced by this, that or which. As an an example:

  1. I can't believe it's raining again today.
  2. I'm about to put on my T-shirt that I bought yesterday.

2. Incorrect spelling "has / since"

Basically, one can say that the word "since" is only used for times:
“Since my 18th birthday I have finally been able to drive a car”.

On the other hand, you use the word "are" when you want to use it as a verb or to describe something:
“Are you always so exhausted after sports lessons?
