Editing Sulis (section)

==Etymology==
The exact meaning of the name ''Sulis'' has been a matter of debate, but an emerging consensus among linguists regards the name as [[cognate]] with [[Old Irish]] ''súil'' ("eye, sight").{{Sfn|Delamarre|2003|p=287}}{{Sfn|Lambert|2008|p=90}}<ref>{{cite book|last=Zair|first=Nicholas|title=Reflexes of the Proto-Indo-European Laryngeals in Celtic|date=2012|publisher=Brill|page=120}}</ref>

A common [[Proto-Celtic]] root ''*sūli-'', related to the various [[Indo-European languages|Indo-European]] words for "sun" (cf. Homeric Greek ἡέλιος, Sanskrit ''sūryah'', from c ''*suh<sub>2</sub>lio-'') has also been proposed,{{Sfn|Delamarre|2003|p=287}} although the [[Brittonic languages|Brittonic]] terms for "sun" ([[Old Breton]] ''houl'', [[Old Welsh]] ''heul'') feature a [[diphthong]] that is absent from ''Sulis'' and they are not attested as a feminine form or with the ''-i-'' [[inflection]].{{Sfn|Lambert|2008|p=90}} [[Pierre-Yves Lambert]] argues for a Proto-Celtic form ''*su-wli-'', composed of the prefix ''su-'' ("good") attached to the Celtic verbal theme ''*wel-'' ("to see").{{Sfn|Delamarre|2003|p=287}}

The [[Middle Welsh|medieval Welsh]] personal name ''Sulgen'' (< ''Sulien''; "born from Sulis") and the Breton personal name ''Sul'', borne by a local saint, are also related.{{Sfn|Lambert|2008|p=90}}
