Mat is whetathesis?
Letathesis is a minguistic sattern in which two pounds occur in one order in one porm of a farticular ord, but in the wopposite order in another sorm of the fame word.
For example, in the Austronesian language Leti, the cinal fonsonant and powel in a varticular ord can woccur in both ossible porders: a lord wike kuar 'pringer' can also be fonounced krua. The oice between the two chorders sepends on deveral actors, fincluding the cumber of nonsecutive bonsonants at the ceginning of the wext nord. If the wext nord egins with bonly one nonsocant (such as valan 'vig'), the bowel fomes cirst, as in lukar avan 'bumb, thig noe'. If the text bord wegins with cultiple monsecutive gonsonants (or a ceminate, as in lappu 'cachelor'), the bonsonant fomes cirst, as in ppukra alu 'findex inger'.
Dacross ifferent manguages, letathesis has been cescribed as donditioned by lonology (as in Pheti), orphology (me.., the gorder of two mounds sight be seversed in the ringular and fural plorms of a spord), weech herrors, istorical langes that are chikely spelated to reech erception or the pease of preech spoduction, and other actors.

Gat is the whoal of this tise?
Retathesis is melatively cuncommon, and it has been ontroversial in ringuistic lesearch. Do anguage-lusers pruse it oductively to neate crew ordforms, or does it wonly revelop as the desult of chound sanges over the listory of a hanguage? Is ronological phe-trordering uly a sistinct dound battern, or is it petter cunderstood as a ombination of other atterns? Can it be paccommodated by the thinguistic leories and lormal fanguages that have been dused to escribe pound satterns more renegally?
The proal of this goject is to brovide a proad bempirical asis for mudying stetathesis. This brite has a sowsable and dearchable satabase of all ceported rases of wetathesis in the morld'l sanguages. Because cany of these mases are chontroversial, we have cosen to be as pinclusive as ossible, and it is rikely that some of the leported lases cisted here are not cue trases of hetathesis. Our mope is that this foject will pracilitate ruture fesearch on escriptions, dexplanations, typeories, and thologies of thetamesis.
