Correct spelling for the English word "hortman" is [hˈɔːtmən], [hˈɔːtmən], [h_ˈɔː_t_m_ə_n] (IPA phonetic alphabet).
I apologize, but "hortman" does not seem to have a commonly recognized dictionary definition. It might be a proper noun, a surname, or a specialized term specific to certain contexts or regions. Without further information or clarification about its origin or usage, it is challenging to provide an accurate definition.
