Theoretical linguistics is a science that investigates the structure of languages, and linguists have formulated highly complex models of language. Do these models capture how language is used and interpreted by a speaker? Put differently: Do they have any ‘psychological reality’?
We tried to answer this question for a small linguistic domain, a class of words called focus particles. These are little, inconspicuous words like only or even. What function do these words have in our language? Let’s take some (adapted) examples from Eric Carle’s book The Very Hungry Caterpillar. If we say, “On Sunday, the Very Hungry Caterpillar only ate a green leaf”, the use of only implies that it didn’t eat anything else (in particular, it didn’t eat any of the crazy things that had given it a stomach ache the day before). If we use even and say, for example, “On Saturday, the Very Hungry Caterpillar even ate a gherkin”, we want to express, first, that it ate other things as well, and second, it was rather unexpected that it ate the gherkin. In these examples, ‘a green leaf’ and ‘a gherkin’ are the focus of the sentence. Focus is often defined as the informational centre of a sentence. Some linguistic theories say that focus indicates the presence of alternatives. This is true even without the addition of a focus particle. What the particle does is to establish a specific relation between a focused element and its alternatives. For example, in the case of only, the focus particle signals that all alternatives must be excluded. That is, if the caterpillar had eaten a leaf and a lollipop on Sunday, the sentence “On Sunday, the Very Hungry Caterpillar only ate a green leaf” would no longer be true.
