 One important discovery of meaning–text linguistics was the recognition that LUs in a language can be related to one another in an abstract semantic sense and that this same relation also holds across many lexically-unrelated pairs or sets of LUs.These relations are represented in MTT as lexical functions (LF).An example of a simple LF is Magn(L), which represents collocations used in intensification such as "heavy rain", "strong wind", or "intense bombardment".
