I put this list together as a student, so you will see some things in here that are quite simple. You will also see some words with *s/l* beside them. These are sound-alikes. I put them in the list, the way it sounded to me, then in the right column I entered the word the way it should be, or entered a possible alternative. There are prefixes, suffixes, drugs, abbreviations,etc. Some words have definitions, some do not. Please let me know if you run across any errors and I will correct them.
