Correct spelling for the English word "more halfprice" is [mˈɔː hˈɑːfpɹa͡ɪs], [mˈɔː hˈɑːfpɹaɪs], [m_ˈɔː h_ˈɑː_f_p_ɹ_aɪ_s] (IPA phonetic alphabet).
The word "more halfprice" does not have an established etymology because it appears to be a combination of two independent words, "more" and "halfprice", without any specific linguistic origins. "More" is an English word indicating additional amount or degree, while "halfprice" is a compound word consisting of "half" (meaning one part of two equal parts) and "price" (originating from Latin pretium, meaning value or cost). The combination of these words in "more halfprice" suggests an emphasis on a further reduction or discount in price, but the term itself does not have a distinct etymology apart from its individual components.
