Questions & Answers about Hvis jeg skriver forkert, bruger jeg viskelæderet med det samme.

Why does the sentence start with Hvis?

Hvis means if.

It introduces a condition:

• Hvis jeg skriver forkert = If I write incorrectly / If I make a mistake when writing

So the whole sentence describes what happens if that condition is true.

A learner might compare it with når (when):

• Hvis = if, under that condition
• Når = when, whenever

In many everyday situations, both can appear in similar contexts, but hvis focuses more clearly on the condition.

Why is it skriver forkert and not something like skriver forkertt or forkerte?

Forkert is an adverb here, meaning incorrectly / wrong.

It modifies the verb skriver:

• jeg skriver forkert = I write incorrectly / I write something wrong

Because it is being used adverbially, it stays as forkert.

Compare:

• et forkert svar = a wrong answer
  Here forkert is an adjective describing the noun svar.
• jeg svarer forkert = I answer incorrectly
  Here forkert functions adverbially.

So in this sentence, forkert is the normal form.
