Correct spelling for the English word "abdoment" is [ˈabdə͡ʊmənt], [ˈabdəʊmənt], [ˈa_b_d_əʊ_m_ə_n_t] (IPA phonetic alphabet).
The word "abdomen" comes from the Latin word "abdomen", which originally referred to the belly or trunk of an animal. It is believed to have derived from the combination of the prefix "ab-" (meaning away or off) and "dere" (meaning to hide or conceal). This probably reflects the idea that the abdomen contains internal organs that are hidden or concealed within the body. The use of "abdomen" to refer specifically to the lower part of the trunk in humans emerged in the English language during the 17th century.
