the word 'taxer' is a transparent english formation built upon the verb 'tax'. the verb itself has a complex history, entering english from old french taxer, which derived from latin taxare, meaning to handle, appraise, or charge. the latin verb is likely a frequentative form of tangere ("to touch"), suggesting a process of repeated handling or assessment. the agent suffix '-er', of germanic origin, is one of the most productive in english for forming nouns denoting a person associated with an action. thus, a 'taxer' is literally "one who assesses or levies a charge," a meaning that has remained consistent from its medieval origins concerning financial imposition to its modern administrative and sometimes figurative usage.
