Forms
quīdam (feminine quaedam, neuter quiddam); indefinite pronoun[1]
Etymology
It is the relative quī (in the pronoun, probably ⟨*quisdam⟩ from quis) with the suffix ⟨-dam⟩, whose origin is uncertain; the same suffix is in quondam.[2][1] Köbler connects it with the PIE particle Proto-Indo-European *de- (“here, then”).[3]
Earliest recorded meaning
It is found from Plautus on: est rēs quaedam quam occultābam tibi dīcere “there is a certain matter I was hiding from you”.[3][2]
Semantic evolution
Quīdam refers to a particular person or thing that is not named: “a certain, someone, something”.[2][4] It can single out an outstanding example of its kind and, qualifying a term, means “a kind of, what might be called” (medium quoddam “a sort of middle”).[2][5]
Accius has an old plural quēsdam.[2]
