Halliday & Matthiessen (1999: 233n):
Because of the vastness of lexis, we do not yet have a general description of lexical metaphorical syndromes or of the location of metaphorical domains within the overall ideation base. But it is possible to discern that a central resource for metaphor is human bodily experience; and that the human body itself, concrete phenomena located in space-time, and features of daily social life are the most favoured metaphorical motifs.Renton (1990: 513-514) lists 37 such motifs, which account for 87 %of the 4215 metaphorical items in his dictionary of metaphor. The most common are human body (23%), animals (9%), sport (4%), food & drink (4%), war A military (4%), buildings (4%), geography (4%), clothes (3%), nautical (3%), religion & biblical (3%), transport (2%), plants (2%), meteorology (2%), science & medicine (2%), colours (2%), commerce (2%), manufacture (1%), and the remaining types 1% or less.The descriptive challenge is to systematise the domains of lexical metaphor, as Lakoff & Johnson (1980) and researchers building on their framework have started to do.
