Copy of which suffix means the process of using an instrument to examine

A suffix is a morpheme or words added at the end of the word to form a new word or change the meaning of the word.

Example, with the suffix - etic (means relating to), an athlete is changed into athletic and energy is changed into energetic which changes the meaning of the word.

Hence, a suffix which means the process of using an instrument to examine is - scopy
