Общая заметка: The traces of s in this etymon are too many to be ignored. It must be admitted, however, that the loss of s in PSl. *justro is irregular. According to Nieminen (1956), the s was lost as a result of dissimilation in syntagms such as *za ustra and *sъ ustra. The main problem of the etymology *h2eus-ro- is not the absence of s but the PSl. acute intonation of the root. I suspect that we are dealing with an instance of contamination here, but for the time being a proper candidate seems to be lacking.

Примечания: {1} In the Psalterium Sinaiticum there is a single occurrence of zaustra `in the morning'. In view of Bulg. zaґstra, Mcd. dzaґstra, this is unlikely to be a writing error. {2} In Древнепольский: we find such forms as justrzejszy `tomorrow's', justrzenka `dawn'. {3} Aušra° 2 is also

Общая заметка: The most plausible etymology for this obscure form involves a connection with Lith. aґusti (1sg. aґudžiu) `weave'. Vasmer (s.v.) reconstructs the suffix as *-slo, but I find *-tlo more attractive. In this case, the correspondence between AP (b) in Slavic and an acute root in Baltic would not pose a problem because the glottal stop originating from Winter's law would be lost in pretonic position (see Derksen 1996: 105-111).
Примечания: {1} As far as I know, this form has only been recorded by Dal', who adds a question mark. The word is illustrated by the sentence Сколъ велико усло? `Много ли наткала'?'
