ELI5: why is someone who carries messages a ‘messenger’ and not a ‘messager’
gpt
As with most circumstances where this occurs in English, it's because the two words actually come from different roots--"message" is derived from Latin, but "messenger" is from Middle Ages French. In some cases they fiddle with the spelling to make the word association that much clearer (see: "isle" and "island", where they added the s to the second word to make it more similar to the first), but in others, they don't.
