   • c. 800–825, Diarmait, Milan Glosses on the Psalms, published in Thesaurus Palaeohibernicus (reprinted 1987, Dublin Institute for Advanced Studies), edited and with translations by Whitley Stokes and John Strachan, vol. I, pp. 7–483, Ml. 102^a15

     Itius anúas ⁊ dus·claid anís; air ní foircnea in fíni hithe neich di anúas, amal du·ngní int aīs sechmaill as·mbeir-som .i. air is cuit adaill ad·n-ellat-sidi in fíni du thabairt neich doib dia thorud.

     They eat it from above and he roots it up from below; for it does not exterminate the vine to eat of anything of it from above, as do the passers-by whom he speaks of, i.e. for it is only a passing visit that they make [lit: ‘that they visit’] to the vine to take something for themselves of its fruit.

This form shows syncope of the second syllable of ithit /ˈiθʲidʲ/ and simplification of /θʲ-dʲ/ to /dʲ/.

Could in principle also be “(s)he eats it”, from ithith + -us and pronounced /ˈitʲiu̯s/ with /tʲ/ regularly from /θʲ-θʲ/. The quote above is so translated by Strachan,[1] but the plural reading (as translated in Thesaurus Palaeohibernicus vol. I p. 345) makes more sense in context.
