They are totally different words, in both meaning and (at least where I live in the USA) pronunciation.
Perhaps because they have a lot of the same letters in roughly the same order I could see where they might confuse someone who first came across them in writing. I can even see where relating them might be a useful mnemonic for people trying to memorize English vocabulary.
However, for those of us who learned them audibly, I assure you there is no confusion. They really bear no relation to each other at all.
