Usage tips
Word structure
The word is made up of the prefix 'un-' (not) and the adjective 'wichtig' (important). This pattern of using 'un-' to form the opposite of an adjective is very common in German (e.g., unglücklich, ungesund).
EXAMPLE
Er war mit dem Ergebnis sehr unzufrieden.
He was very dissatisfied with the result.
Use in a sentence
As an adjective, 'unwichtig' (unimportant) can stand before a noun or be used with verbs like 'sein' (to be), 'werden' (to become), or 'finden' (to find/consider). Both uses are very common.
EXAMPLE
Das ist eine völlig unwichtige Information.
That is a completely unimportant piece of information.
For whom is it unimportant?
To express for whom something is unimportant, you use the preposition 'für' (for) followed by the accusative. 'Unwichtig' is often intensified by adverbs like 'völlig' (completely) or 'gänzlich' (entirely).
EXAMPLE
Für mich ist es völlig unwichtig, was andere Leute denken.
For me, it is completely unimportant what other people think.

unwichtig vs klein
small
'klein' and 'unwichtig' can both say that something is not very important. In this use, 'klein' is often milder and can also simply mean that something is not very serious or not very large. 'unwichtig' is more direct: something does not play an important role, and you do not need to worry much about it. In conversation, 'ein kleines Problem' (a minor problem) often sounds friendlier than 'ein unwichtiges Problem' (an unimportant problem). If you want to say clearly that something has no significance, 'unwichtig' is more precise.
unwichtig
Er sagt, dass die Farbe des Koffers für die Reise unwichtig ist.
He says that the color of the suitcase is unimportant for the trip.
klein
Wegen eines kleinen Fehlers muss er die ganze Aufgabe noch einmal prüfen.
Because of a minor mistake, he has to check the whole task again.
