How to Interpret OED Entries

Note the word's etymology. What is the word's language of origin? Latin, Saxon, Greek, French, etc.?

Note the word's definitions. How many different ways has the word been defined over time? Does the word appear to have had a complicated history? According to the date your literary text was published, how many definitions would have been available to the text's author? Note all definitions -- even conflicting ones -- that were in use at the time of your literary text's publication. How do some of these other definitions affect your sense of what the word or passage in your literary text could mean?

Note the word's historical usage. What is the earliest known usage of the word? How has the spelling changed over time? Which usages are familiar to you? Which usages by canonical authors or well-known literary texts might merit your attention? Keep in mind that some usages might have become popular after your literary text was published. Are there any other words or allusions you need to look up to close read the text?
