すぐ

Etymology 1
From, from. Cognate with 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

Likely derived from root verb form sugu. The expected adjectival or adverbial form would be sugi, but there is evidence for sugu used in this way in ancient eastern dialects.

Notably, the modern verbs and  derived from sugu (see further below) have shared underlying senses of “going through; directly; without stopping or turning”, indicative of this common root.
