Ludwig's WRAP-UP
In summary, "wherein each" is a formal phrase functioning as a relative adverb, used to specify a condition or attribute that applies individually to elements within a group. As Ludwig confirms, this phrase is grammatically correct and frequently appears in scientific and technical contexts. While alternatives like "in which each" exist, "wherein each" lends a more formal tone. When using this phrase, ensure the attribute truly applies individually to each element and not collectively to the group. Its frequency is high, and it is most often found in "Science" and "News & Media" sources. Considering its register, it might be better to replace it with a less formal version when the text has a less elevated and sophisticated tone.
