Correct spelling for the English word "iritomy" is [ɪɹˈɪtəmɪ], [ɪɹˈɪtəmɪ], [ɪ_ɹ_ˈɪ_t_ə_m_ɪ] (IPA phonetic alphabet).
Apologies, but it seems that "iritomy" does not have an existing dictionary definition as it may be a term that is specific to a particular field of study or does not have widespread usage. However, based on the word components, we can attempt to offer a speculative definition:
"Iritomy" may be derived from the prefix "ir-" meaning "not" or "without," and the root word "itomy," which could possibly be related to "otomy," a suffix meaning "a cutting, incision, or surgical procedure." Therefore, "iritomy" could potentially refer to a process or technique that involves the absence of a surgical incision or cutting during a medical procedure.
However, it is important to note that without a context or authoritative source, this definition is purely speculative, and the actual definition may be different or non-existent. To acquire a definitive understanding of "iritomy," it may be beneficial to consult subject-specific resources, professionals, or experts in relevant fields.
