Excuse me for my ignorance, as this is a very basic question.I know very little about ships and jobs. :
In a book, I read the following phrase:
The flowers were ceremoniously transferred to Janin, a junior deck officer, who delivered them and then sought out Claude Dessard.
Regarding Janin: what does “a” junior deck officer do? Is he like an errand boy or something?
In this case, Claude Dessard is the Third Mate (the junior deck officer).
Did I miss the point or is this just another case of a writer writing about something he doesn’t know much about?
