expertus (Latin)
Where does "expertus" come from?
The Latin adjective 'expertus' originated as the perfect active participle of the verb 'experior'[1]. Although it functioned grammatically as a participle for the active verb 'experior', meaning 'to test' or 'to experience', it carried a passive sense that defined someone as 'experienced'[1]. The underlying root is likely connected to the Proto-Indo-European '*per-', meaning 'to go through'[2]. However, scholars like De Vaan have alternatively proposed a link to the Latin verb 'pario', which means 'to give birth to' or 'to produce', and traces back to the Proto-Indo-European root '*perh3-'[2].
Open questions
- The derivation from the Proto-Indo-European root meaning to go through is challenged by scholars who prefer an origin connected to the verb for giving birth or producing. [2]
