gulti

Cognate with Latvian gul̃t (“go to bed”). Related to guolis (“lair, den”). Derksen connects this etymon with dialectal gvaldýti (“cram, pack”), gvãlis (“lair, den”), which means the -u- must go back to Proto-Indo-European *-u̯-. The root may therefore by Proto-Indo-European *gwel-, *gul-.[1]

In view of this reconstruction, we may have to reject connections with Tocharian A klā-, klāw- Tocharian B klāy- (“fall, collapse”), Sanskrit ग्लाति (glāti) ग्लायति (glāyáti, “be exhausted, weary”), which assume a zero-grade *gʷl̥-.[2]

An alternative view is that of Robinson, who, in view of lėgti ("weaken, cease", also "lay down"), suggests a connection by metathesis with Proto-Slavic *legti (“to lie”), from *legʰ-.[3] Compare kepti : Proto-Slavic *pekti (“to bake”).
