Correct spelling for the English word "initiatrix" is [ɪnˌɪʃɪˈe͡ɪtɹɪks], [ɪnˌɪʃɪˈeɪtɹɪks], [ɪ_n_ˌɪ_ʃ_ɪ__ˈeɪ_t_ɹ_ɪ_k_s] (IPA phonetic alphabet).
The word "initiatrix" is derived from the noun "initiator" combined with the suffix "-trix".
The noun "initiator" comes from the Latin verb "initiare", meaning "to begin", which itself originates from the word "initium", meaning "beginning" or "entryway".
The suffix "-trix" is the feminine form of the suffix "-tor" and is used to indicate the doer or performer of an action. It is often added to words to form female gender-specific nouns.
Therefore, when the suffix "-trix" is added to "initiator", it creates "initiatrix", a term used to refer to a female who performs the action of initiating or beginning something, especially in the context of rituals, ceremonies, or secret societies.
