In an article titled "Six top grammar reads" by Mark Brenchley & Ian Cushing for tes.com (6/18/18), the authors state: ""Cohesion" is perhaps the most important linguistic concept there is, essentially comprising how the linguistic features of a piece of writing combine to make it what it is: a unified orchestration of meaning. Originally published in 1976, Halliday and Hasan's groundbreaking work remains the standard textbook for this topic. Put simply, it is jam-packed with detailed, concrete discussions of all the different resources English has for making sure each piece of writing hangs together."
