The most common German word for “confusing” is “verwirrend” and describes disorienting or befuddling situations or things:

– “Diese Anweisungen sind total verwirrend.” – “These instructions are totally confusing.”
– “Er hat mich komplett verwirrt.” – “He (has) completely confused me.”

Another word for “confusing” is “unübersichtlich” (essentially “unclear”, which is used when things are not in proper order and thus bewildering):

– “Dein Text ist so unübersichtlich.” – “Your text is so cluttered/messy/disorganized/confusing.”

Lastly, the word “irritierend”, which DOES NOT mean “irritated” or “irritating” is also used to express confusion or disconcertedness:

– “Ich bin ein bisschen irritiert.” – “I am a little perplexed.”
