This year, 2021, marks 60 years since Halliday published his seminal paper “Categories of the theory of grammar” in WORD. This paper outlined many of the key categories, scales and principles that underpinned the development of what has come to be known as Systemic Functional Linguistics (SFL). Since that time, SFL has continually evolved as it engaged with an ever-increasing number of languages, modalities of communication and practical applications. To celebrate this anniversary, three special issues have been organized that aim to push SFL once more, this time in relation to the grammar of nominal groups.
The papers in this series explore a number of issues that have arisen in relation to nominal groups as more languages have been described in SFL. We are grateful to our colleagues who have taken time to contribute to these issues during what have been especially challenging times in academe and beyond.
