Translation:You are stupid.
It really can be annoying for beginners. As you get used to Klingon, it'll be easier because you will get used to Klingon spelling patterns. It is impossible to have three consonants in a row like that, so the middle letter must be an I. Once you have internalized the pattern, you will just naturally see l's and I's even when the font doesn't distinguish them at all. For now you just have to try to see that little curle at the bottom of the l.
