mutual intelligibility even between close neighbours. That divergence has been quite extreme: e.g. the 17 Torres-Banks languages of north Vanuatu (<10,000 speakers in total) show higher rates of lexical divergence in basic vocabulary than all of Germanic,
or all of Slavic, or all of Romance, in a similar time frame </span><span style="font-size:7.5pt;font-family:"Tahoma",sans-serif"> (see <a href="https://marama.huma-num.fr/data/AlexFrancois_2011_JHL1-2_Social-ecology_Vanuatu.pdf#page=29" target="_blank">F2011:203</a>).</span><span style="font-family:"Tahoma",sans-serif"><o:p></o:p></span></p>

a “trend towards word-for-word translatable codes” (Gumperz & Wilson 1971: 165). Achieving cross-linguistic structural isomorphism makes it cognitively easier for speakers to learn and speak other language varieties. Also, by limiting the risk of semantic
loss in translation, such parallelism increases the chances for successful communication events.”</span></p>

<div>
<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif">The extreme divergence we see cannot merely be explained by geographical isolation, because the languages of north Vanuatu (or those of Vanikoro) have always remained in contact, with a tradition
of encouraging linguistic exogamy, and (egalitarian) multilingualism even within a single family. This constant social contact should have preserved the original linguistic unity, yet what we see, paradoxically, is a strong signal of linguistic divergence.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif">My understanding is that linguistic divergence here results from a spontaneous process of selection, driven by a social ideology that promotes the strengthening of local identities through contrasts in
their linguistic (and cultural) profiles. The processes of divergence serve an emblematic function, that of indexing distinct communities anchored in space. (While the stratified societies of Europe tend to index social groups through sociolects and stylistic
registers, the egalitarian societies of Melanesia invest in the diatopic dimension, i.e. the distribution of lects in geography.)<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif">The selection process itself is, I believe, subconscious; but indirectly, through an "Invisible hand" mechanism (Keller 1989), it serves a purpose of social differentiation of which speakers
are fully aware. This is why the linguistic variants that are selected for emblematic purposes are the ones that are the most salient to speakers' attention: phonetic shibboleths and phonological patterns; sound change; lexical replacement, through the
selection of non-cognate synonyms. <o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-family:"Tahoma",sans-serif">The end result of these competing forces is that word forms tend to diverge from place to place, whereas semantic structures are inaccessible enough to speakers' awareness that they are left

Subject: [Lingtyp] The purpose of convergence and divergence?<br>

Dear Typologists,<br>
<br>
I would appreciate it if you could point to me the literature discussing the purpose of linguistic convergence and divergence.<br>
Do they happen simply because they happen - or do they serve any purpose? Do they bring any benefit?<br>
For example if my lect changes based on to what my neighbors are speaking, it's an interesting phenomenon, but what good does it do? Does it make me more suitable as a neighbor? Does it make it more easier for me to learn their (dominant) lect? Does it facilitate
code-switching?<br>
Same about divergence - if a group that split away from a bigger group changes their lect in a divergent manner, then what benefit does it bring? Does it solidate their group identity? Does it help to identify an in-group member?<br>
These questions have been stuck in my head for quite a long time now and I would be grateful if you could provide me previous insights on such questions.<br>
<br>
From the Netherlands,<br>
Ian<br>
