Processing considerations seem to be a major factor constraining<br />

cross-linguistic variation. An example from <strong>the</strong><br />

early generative literature is <strong>the</strong> difficulty <strong>of</strong> processing selfembedded<br />

constructions, for instance where a relative<br />

clause is included internally within ano<strong>the</strong>r relative clause,<br />

as in <strong>the</strong> boy [that <strong>the</strong> man [that I saw] caught] took <strong>the</strong><br />

apple, although a slight change <strong>of</strong> construction to avoid <strong>the</strong><br />

self-embedding produces a readily interpretable sentence:<br />

<strong>the</strong> apple was taken by <strong>the</strong> boy [that was caught by <strong>the</strong> man<br />

[that was seen by me]]. A detailed <strong>the</strong>ory relating word<br />

order universals (both absolute and tendencies) to processing<br />

constraints is developed by Hawkins (1994).<br />

This leads into <strong>the</strong> area <strong>of</strong> functional motivations for language<br />

universals, including not only <strong>the</strong> needs <strong>of</strong> processing<br />

but also o<strong>the</strong>r considerations from SEMANTICS and PRAG-<br />

MATICS. For instance, <strong>the</strong> universal stated above that “if a<br />

language has distinct reflexive pronouns in <strong>the</strong> non-third<br />

person, <strong>the</strong>n it also has distinct reflexive pronouns in <strong>the</strong><br />

third person” does not have any obvious formal explanation;<br />

this universal is no simpler in formal terms than its empirically<br />

incorrect opposite “if a language has distinct reflexive<br />

pronouns in <strong>the</strong> third person, <strong>the</strong>n it also has distinct reflexive<br />

pronouns in <strong>the</strong> non-third person.” But as soon as one<br />

starts thinking about <strong>the</strong> semantic function <strong>of</strong> pronouns, a<br />

plausible explanation emerges. First- and second-person<br />

pronouns are uniquely determined by <strong>the</strong> speech situation,<br />

with <strong>the</strong> speaker referred to in <strong>the</strong> first person and <strong>the</strong> hearer<br />

in <strong>the</strong> second person. They thus do not change within an<br />

utterance, and whe<strong>the</strong>r a language says I hit myself or I hit<br />

me does not affect <strong>the</strong> content, that is, marking reflexivity is<br />

in a sense redundant in <strong>the</strong> first and second persons. Third<br />

person pronouns can potentially refer to any o<strong>the</strong>r entity in<br />

<strong>the</strong> universe <strong>of</strong> DISCOURSE, so it is useful to have different<br />

forms that enable distinctions among potential referents to<br />

be maintained, as in <strong>the</strong> case <strong>of</strong> he i hit himself i versus he i hit<br />

him j . Quite generally, as predicted, pronoun systems tend to<br />

make more referential distinctions in <strong>the</strong> third person than in<br />

<strong>the</strong> o<strong>the</strong>r persons, as when English distinguishes gender in<br />

<strong>the</strong> third person singular (he, she, it) but not in <strong>the</strong> first person<br />

(I) or <strong>the</strong> second person (you). Comrie (1984) shows<br />

how certain language universals can plausibly be related to<br />

pragmatics, for instance universals <strong>of</strong> imperative formation<br />

to <strong>the</strong> pragmatic function <strong>of</strong> imperatives in encoding <strong>the</strong><br />

speech act <strong>of</strong> directive (Searle 1969): because directives<br />

require that <strong>the</strong> addressee carry out a certain action, many<br />

languages have a constraint that only imperatives with <strong>the</strong><br />

addressee as agent are possible, that is, <strong>the</strong>y allow <strong>the</strong> equivalent<br />

<strong>of</strong> eat <strong>the</strong> bread! but not <strong>of</strong> be eaten by <strong>the</strong> lion!; no<br />

language shows <strong>the</strong> inverse pattern.<br />
