Correct spelling for the English word "kinch" is [kˈɪnt͡ʃ], [kˈɪntʃ], [k_ˈɪ_n_tʃ] (IPA phonetic alphabet).
The word "kinch" is a slang term that originated in Irish English. Its exact etymology is not well-documented, but it is believed to derive from the Irish word "cinnse", meaning "mischievous person" or "rogue". Over time, "cinnse" transformed into "kinch" and came to be used specifically to refer to a small, clever, and mischievous child. The term has also been used in Irish-American communities. However, it is worth noting that "kinch" is not widely recognized outside of Irish English and Irish-American vernacular.
