255: Messenger not Messager Aug 20, 2015
Often to indicate someone who does a given action in English, one simply
needs to add an '-(e)r' or '-or'. There are some exceptions to that
rule; over time people add sounds to make certain words easier to
pronounce: someone who sends a message is not a 'messager', but a
'messenger', and the same applies to the word, 'passenger'.
