Is there any evidence that the third person singular -s can be traced back to a lexical item before it became an inflection ? I am trying to see if the theory of grammaticalization applies to its diachronic process. Any information would be most helpful. Thanks so much.

Almost certainly not. The usual 3rd person singular inflection in Old English was -th or -eth and it looks as if its replacement by -s came about by a process of sound change. |

I will promote my comment to an answer here too. PIE -ti -> PGmc -di/-ði -> AS -t/-ð/-þ -> ME -th (Southern)/ -s (Northern) -> ModE -s The Northern -s came from the influence of Norse mediopassive -sk; eventually the Northern usage became standard in Modern English. According to this, the form has been inflectional at least back to late PIE. |
