|Attestation:||SL-2.1 (siraku:̣þurti) (1)|
Assuming that the form is Raetic, as indicated by the alphabet used, it is not otherwise attested in the Raetic corpus, but may qualify as an individual name in °u. It is not accompanied by the usual patronym in -nu, but see þurti and Raetic onomastics for alternative solutions. The auslaut °ku might be analysed as the ending of deverbal nouns -ku with an otherwise unattested verbal base sir(a)-, but deverbal nouns never occur in sentence-initial position.
Alternatively, the following Celtic etymologies have been suggested: Marstrander 1925: 51 f., expecting a Celtic name, compares serrancu in CIL XIII 90 and reads a nom.sg.m. n-stem Celtic PN in -u containing *sīr- 'long, lasting, constant'. For objections see Markey 2001: 110 f., who reads Celtic siragu < *sīr-agō(n) 'astral priest' with a Celtic vrddhied composition form *sīr- 'star' + nom.sg. n-stem *agō(n) 'priest'.
Compared with a Scythian PN *Sirakō by Altheim & Trautmann 1939: 43 (evidence see there).
