Reconstruction:Proto-Celtic/tullos

This Proto-Celtic entry contains reconstructed terms and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.

Perhaps from earlier *tux-slo-, from Proto-Indo-European *tuk-slo-, from the root *tewk- (“to push, press (into), beat; to pierce, perforate”), an extended form of *(s)tew-. However, the attested Celtic reflexes show no trace of the presumed *x.^[1]
