なんか and なんて are colloquial expressions used to convey a range of emotional nuances – from self-deprecation and dismissal to surprise and emphasis. While they overlap in some uses, each has its own tendencies.
なんか is the colloquial form of なにか ("something"), but in everyday speech it has evolved well beyond that meaning. It is used to:
When placed after a noun, なんか downplays or dismisses the importance of that thing or person. It often translates to "something like," "the likes of," or "such a thing as."
なんか is extremely common as a filler word in casual speech, similar to English "like" or "kind of." It softens what follows and makes it sound less direct.
なんて is used when the speaker finds something surprising, unbelievable, or wants to emphasize their emotional reaction. It can also be used to dismiss something, similar to なんか.
Here, なんて follows a clause and highlights that the preceding fact is unexpected or remarkable.
Both can express dismissal or belittling, and in that usage they are largely interchangeable:
However, なんて has the additional ability to follow entire clauses to express surprise or disbelief, which なんか cannot do. And なんか is more common as a vague filler word at the start of sentences, which なんて is not used for.
