This book explores the gap that has developed between two sides in linguistics: the formal tradition and the functional tradition. It discusses fundamental issues such as tense, aspect and action by examining and comparing insights from the two traditions with a view to determining whether there are any possibilities of future bride-building between the two approaches. This study focuses on comparing the actual output of different linguistic approaches and examines their 'usefulness'. A major aim is, therefore, to evaluate and identify the most useful approach.
