In German, a medial capital I (German: Binnen-I) is a non-standard, mixed case typographic convention used to indicate gender inclusivity for nouns having to do with people, by using a capital letter 'I' inside the word (Binnenmajuskel, literally "internal capital", i.e. camel case) surrounded by lower-case letters. An example is the word LehrerInnen ("teachers", both male and female). With a lower case I in that position, Lehrerinnen is just the standard word for "female teachers".
