suādeō
suādeō uit.-lat.
From a Proto-Indo-European causative verb in *-éyeti from the root *sweh₂d- (“sweet”),[1][2][3] hence literally, “to make sweet, pleasing”. The stem of the original verb may have been either the zero-grade *suh₂d-éyeti,[2] as in Sanskrit सूदयति (sūdáyati, “to make tasty”), or the o-grade *swoh₂d-éyeti,[3] but in the end it was secondarily replaced with the full grade by influence of the related adjective suāvis (“sweet”).[2][3]
- (Classical Latin) IPA(key): /ˈsu̯aː.de.oː/, [ˈs̠u̯äːd̪eoː]
- (Classical Latin) IPA(key): /suˈaː.de.oː/, [s̠uˈäːd̪eoː]
- (modern Italianate Ecclesiastical) IPA(key): /suˈa.de.o/, [suˈäːd̪eo]
- Note: while the word generally scans with a glide in classical poetry, the rare pronunciation of the u as a vowel (in hiatus) is attested as early as Lucretius (see quotations). Compare the similar phenomenon in suāvis, which Romance languages reflect with a hiatus.
