Do Word Meanings Exist?

My contribution to this discussion is to attempt to spread a little radical doubt. Since I have spent over 30 years of my life writing and editing monolingual dictionary definitions, it may seem rather odd that I should be asking, do word meanings exist? The question is genuine, though: prompted by some puzzling facts about the data that is now available in the form of machine-readable corpora. I am not the only lexicographer to be asking this question after studying corpus evidence. Sue Atkins, for example, has said “I don’t believe in word meanings” (personal communication). It is a question of fundamental importance to the enterprise of sense disambiguation. If senses don’t exist, then there is not much point in trying to ‘disambiguate’ them – or indeed do anything else with them. The very term disambiguate presupposes what Fillmore (1975) characterized as “checklist theories of meaning.” Here I shall reaffirm the argument, on the basis of recent work in corpus analysis, that checklist theories in their current form are at best superficial and at worst misleading. If word meanings do exist, they do not exist as a checklist. The numbered lists of definitions found in dictionaries have helped to create a false picture of what really happens when language is used. Vagueness and redundancy – features which are not readily compatible with a checklist theory – are important design features of natural language, which must be taken into account when doing serious natural language processing. Words are so familiar to us, such an everyday feature of our existence, such an integral and prominent component of our psychological makeup, that it’s hard to see what mysterious, complex, vague-yet-precise entities meanings are.
