Correct spelling for the English word "Puplican" is [pˈuːplɪkən], [pˈuːplɪkən], [p_ˈuː_p_l_ɪ_k_ə_n] (IPA phonetic alphabet).
The word "Publican" comes from the Latin word "publicanus", which itself was derived from the earlier Latin term "publicum" meaning "public". In ancient Rome, a publicanus referred to a tax collector or a person who held the contract for collecting public taxes on behalf of the Roman government. This implied that they were responsible for collecting revenue from various sources such as customs duties, tolls, and other taxes. Over time, the term "Publican" was adopted into English to refer to tax collectors as well, especially during the time of biblical narratives in the New Testament.
