premise: Although L has, in addition to the names, abbreviations, and only a few pages of miscellaneous materials'Handbook of Style, Ten Vexed points in English grammar'and some tables of moneys, weights and measures, etc., W has short sections on Foreign Words and Phrases (most of which are dispensable), Signs and Symbols, and Style, as well as one of those interminably boring listings of Colleges and Universities that clutter up most American college dictionaries.
hypothesis: None of these have any foreign language content.
