History of the English language
theword (sentence), they just change places. It is this feature that allows psycholinguists
to infer that words and sentences are preassembled in the mind: all sounds are there but the
order gets mixed up in the process of actual uttering/pronouncing.
NB! Slips of the tongue in which sounds of a word or sentence are not dropped but merely
change places
1) are made possible by preassembling and therefore
2) serve as evidence of preassembling.
What causes slips of the tongue, includingmetathetical slips of the tongue, in the first place,
and why some people are more prone to them than others is not yet clear: more needs to be
known about how the brain works. However, for the present purposes this question is
immaterial
Why do metathetical forms oust old forms?
