deserter

the word "deserter" is built upon the verb "desert," which entered english in the late 15th century from the french déserter, itself derived from the latin desertare, a frequentative form of deserere. deserere is a compound of the prefix de- (meaning "completely, away") and serere (meaning "to join, link together"), thus carrying the literal sense of "to unjoin, to sever a connection." the agent suffix "-er," of germanic origin, is then appended to denote a person who performs the act of abandoning. the term's specific application to military personnel who abandon their post without leave became prominent in the 17th century, solidifying its modern sense of one who violates a duty or allegiance.

Structure: desert (abandon) + er (agent suffix) "desert" originates from the Latin verb deserere, meaning "to abandon, forsake, leave". "er" is an agent noun suffix from Old English -ere, used to form nouns indicating a person who performs an action.
