I like this piece by content designer, Amy Hupe, because it acknowledges the nuances of language and even plain English. Yes, in most cases, jargon should be avoided. But jargon can empower people and communities too.
UX writing: making our microcopy clear, concise and useful
Miles Taylor, now at Torchbox, wrote this while at University of Bristol. It comes from having pulled a load of information together to try and explain the benefits of UX writing and clear content to internal project teams. This is a job that often seems to fall to us content folk. Plain language? Explain yourself!
This is a great list of complex words with some suggestions for more human – clearer – alternatives. It was put together by Deanna Horton, a content designer currently at Shopify.
