The WP:RS policy does not classify dictionaries as tertiary sources.  They are not in fact compendia, encyclopedias, textbooks, and other summarizing source.  They are secondary sources because they are the results of scholars who research primary sources in order to determine the meanings of words.  In fact the Oxford English Dictionary is the most reliable secondary source for the meanings of words in the English language.  It is common sense that if one wants to know the meaning of a word that one consults a dictionary.  Ironically, the twelve sources presented in the footnotes do not support the interpretation that User:Collect has provided.
Also could we all please assume good faith.
