Accepted Answer

Valerie, 
it is an unusual one, but ‘ soudain ‘ is used as an adverb in its own right, as well as being an adjective. 
It is a synonym of ‘ soudainement ‘  as an adverb and can translate to English as ‘suddenly’

Answer

Thomas,

What is wrong ? Are you just referring to the inadvertent misspelling in the original question ?

The use of soudain as an adverb is correct, as would the use of soudainement have been.
