english: So, in a quite understandable need for distraction, you're doodling and thinking more about what the plural of "series" should be than about the topic at hand: "serieses," "seriese," "seriesen," and "serii?"
non_english: nadenkt over het meervoud van 'oneindigheid' in plaats over het onderwerp:  oneindigheids, onneneindigheid? Zou het enkelvoud 'oneindig' of 'oneind' moeten zijn?
