In situ

In situ (/ɪn ˈsɪtjuː, - ˈsaɪtjuː, - ˈsiː-/; often not italicized in English)^[1]^[2]^[3] is a Latin phrase that translates literally to "on site"^[4] or "in position."^[5] It can mean "locally", "on site", "on the premises", or "in place" to describe where an event takes place and is used in many different contexts. For example, in fields such as physics, geology, chemistry, or biology, in situ may describe the way a measurement is taken, that is, in the same place the phenomenon is occurring without isolating it from other systems or altering the original conditions of the test. The opposite of in situ is ex situ.
