IPA: /ˌaɪ.dɛn.tɪ.fɪˈkeɪ.ʃən/
KK: /ˌaɪdɛntɪfɪˈkeɪʃən/
The process of recognizing or proving who someone is or what something is.
The identification of the suspect was crucial for the investigation.
Identification → It is formed from "ident" (from Latin "idem", meaning the same) and "-fication" (from Latin "facere", meaning to make). The word refers to the process of making something the same or recognizing it as the same as something else.
Think of 'the same' ('idem') being 'made' ('facere') into a recognition process — that's what identification means.
