The word **取证** is formed through the combination of two distinct characters: **取**, meaning "to take" or "to obtain," and **证**, meaning "evidence" or "proof." Together, they create a verb-object compound word where the first character (**取**) acts as the action and the second character (**证**) functions as the object of that action. Thus, the literal and functional meaning of **取证** is "to obtain evidence," specifically referring to the formal process of evidence collection, most commonly within legal, investigative, or forensic contexts. This formation follows a standard and highly productive grammatical pattern in Chinese for creating precise terminology by logically combining semantic units.
