Other things to note
- The OED does not include proper names unless they are widely used in a particular context (for instance, "Chamberlainism," "Shakespearian").
- Letters of the alphabet each have their own OED entry, discussing the history of each letter in typography and usage.
- Initialisms are sequences of letters that refer to a full expression ("USA" = United States of America).
- Acronyms are initialisms that are now words: for instance, NASA is now a word itself, and is no longer only short for the National Aeronautics and Space Administration. (You can view a list of acronyms in the OED here.)
- Abbreviations are shortened words ("Rev.", "p.s.").
- Affixes involve adding something to make an entirely new word: "pro-," "re-" and so on. These will usually have their own entry.
- Ghost words are words that were originally misspelled or misprinted, made their way into the English language, and now are considered spurious. (The OED currently lists about 400 words which originated "in error," some of which are ghost words.
