"The elderly people drink coffee and tea."
Translation:Die Senioren trinken Kaffee und Tee.
Not here. It's a term for old people used by young people who are afraid to say "old"-- or a term used by advertisers who are afraid to use the term "old." "Seniors" are people in their last year of an academic program. "Senior citizen" is only slightly (very slightly) less offensive. There's nothing wrong with "elderly people" "the elderly" or "elders" (although that has a lot of church connotations). I was taught as a child to use the term "elderly people."
