What does mongrel mean?
A mongrel is a dog of mixed breed, particularly one that does not belong to a recognized pedigree breed. In this canine sense, the term can be a straightforward description of a dog's breeding, as in “mongrel dog,” although it may occasionally sound dismissive. The word also has a long history as an offensive label for people considered to have mixed ancestry or to belong to an allegedly impure group. That sense is openly derogatory, carries racial and ethnic connotations, and is not acceptable in ordinary respectful speech. Although “mixed-breed dog” and “crossbreed” can convey the relevant canine meaning without the same disparagement, “mongrel” remains a familiar and distinct term. It is especially associated with descriptions of stray or working dogs whose ancestry is unknown and whose appearance does not correspond to a standardized breed.
A dog of mixed or unknown breed, especially one without a recognized pedigree.
"The mongrel quickly became a familiar sight in the neighbourhood."
Often neutral or mildly disparaging in reference to dogs; “mixed-breed dog” is a fuller, less pejorative alternative.
A person derogatorily characterized as being of mixed ancestry or as belonging to an allegedly impure group.
"The historical text used “mongrel” as a contemptuous racial label."
This sense is an offensive slur and should be used only when discussing the term or quoting historically offensive language.
The regular plural is used for both the canine and derogatory human senses.
"Two mongrels followed the hikers along the forest path."
