Correct spelling for the English word "Doctress" is [dˈɒktɹəs], [dˈɒktɹəs], [d_ˈɒ_k_t_ɹ_ə_s] (IPA phonetic alphabet).
The word "doctress" is formed by adding the suffix "-ess" to the root noun "doctor". The word "doctor" itself has Latin roots and originally comes from the Latin word "doctor" which means "teacher" or "instructor". It was derived from the verb "docēre", meaning "to teach". Over time, the term "doctor" evolved to refer specifically to someone who has obtained a higher level of education, particularly in the medical field. Consequently, "doctress" can be considered the feminine equivalent of "doctor", indicating a woman who has achieved the same level of expertise or possesses a doctorate degree. However, it's important to note that the term "doctress" is not widely used in modern English and is considered outdated.
