However, some possible options include:
* Preceptress: This is a direct feminine form of "preceptor," but it sounds somewhat archaic and is rarely used today.
* Female Preceptor: This is a clear and straightforward way to specify the gender of the preceptor.
* Instructor: This is a general term for a teacher, and it is gender-neutral.
* Mentor: This word has a slightly different connotation than "preceptor," but it is also a suitable term for a female teacher or guide.
Ultimately, the best option will depend on the context and the desired level of formality.
