II2 TAŞNİF STYLE GUIDE There are different implications when writing out the decade as opposed to using numerical figures to express it. The following description is from the 2016 Oxford Guide to Style: When the name of a decade is used to define a social or cultural period it should be written as a word (some styles use an initial capital). The difference between labelling a decade the twenties and calling it the 1920s is that the word form connotes all the social, cultural, and political con- ditions unique to or significant in that decade, while the numerical form is simply the label for the time span. So, the frivolous, fun-loving flappers of the twenties, but the oys- ter blight of the 1980s.
