From “trash” to “rubbish” and back to “trash” (part two)
In the beginning, words for things wasted or thrown away tend to denote some concrete refuse and only later acquire a generic meaning. Yet, when several synonyms share the field, they are seldom fully interchangeable. Thus, trash, rubbish, junk, offal, and garbage either refer to different kinds of discarded objects or have different stylistic overtones. One also notices with some surprise that in Modern English, all such words are borrowings.
