4. English todaymessenger

From Middle English messengere, messingere, messangere, from Old French messanger, a variant of Old French messagier (French messager), equivalent to message + -er. Doublet of messager. Displaced native Old English boda (“messenger, envoy”) and ǣrendraca (“messenger, ambassador”). For the replacement of -ager with -enger, -inger, -anger, compare passenger, harbinger, scavenger, porringer. This development may have been merely the addition of n, or it may have resulted due to contamination from other suffixes such as Middle English -ing and the rare Old French -ange, -enc, -inge, -inghe (“-ing”) for Old French -age (“-age”).
