The 'impersonal' pronoun in Germanic and Romance languages seems to come from one of two paths:
Cognate with the word for 'man'
- Proto-Germanic: *mann-
- Dutch: men
- German: man
- Old English: man (< mann)
- Latin: homō
- French: on (< om < hom) use infl. by germanic
- Catalan: hom (< home) infl. by germanic
Cognate with the word for 'one' (number)
- PIE: *óynos
- German: einer
- Latin: ūnus
- Spanish: uno
- Asturian: ún, unu
Is the English impersonal pronoun 'one' derived from the English word for the number, or from French on (as suggested by the OED)?
