Institutionalized utterances, literature, and language teaching
Linguists have recently suggested that a large proportion of linguistic performance in naturally acquired languages is enabled by the internalization of a huge number of institutionalized utterances, or lexical phrases, or fixed and semi-fixed expressions. This research parallels the discovery, earlier this century, of the oral-formulaic nature of Homeric poetry. Furthermore, although written literature (as opposed to oral epic poetry) is generally assumed to be anything but formulaic, it can be shown that it too necessarily contains a lot of institutionalized expressions, or at least transformations of them, and that our own repertoire of memorized phrases almost certainly comes from literary as well as oral sources. Foreign language teachers clearly need to give serious consideration to the prevalence of lexical phrases, in both speech and writing. Literature can be used in the foreign language classroom as (among many other things) a source of institutionalized phrases.
