Pronunciation: [mˈɜːl] (IPA) 
Merle is a word that can cause confusion when it comes to spelling. It is pronounced /mɜːrl/ (MUHRL) and is most commonly used as a name for a type of dark-colored bird. The word has been borrowed from French, and its spelling was influenced by both French and Old English spellings. Merle is sometimes mistakenly spelled as "murl" or "merl." However, the correct pronunciation is essential to ensure its proper recognition and understanding.
Merle is a noun that can refer to two distinct definitions. In the context of ornithology, it is a term used to describe a type of small songbird belonging to the thrush family, characterized by dark plumage with a white or speckled breast. This definition is commonly applied to European blackbirds (Turdus merula) or similarly colored species. It is worth noting that in North America, the term merle is more commonly associated with certain breeds of dogs and does not refer to a bird.
In the context of dog breeding, merle denotes a coat pattern characterized by a marbled or mottled appearance, often consisting of a combination of patches or flecks of two or more colors. The patterns can vary widely, ranging from solid patches to intricate marble-like swirls. Breeds commonly associated with the merle coat pattern include Australian Shepherds, Border Collies, and Great Danes, among others.
Overall, merle refers to either a type of songbird in the thrush family, particularly the European blackbird, or a coat pattern observed in various breeds of dogs, featuring a mottled appearance with patches or flecks of different colors.

The word "merle" has a multifaceted etymology. It originated from Old French "merle", which means "blackbird". In turn, Old French derived it from Latin "merulus", meaning the same.
The Latin term "merulus" itself was borrowed from an earlier language, believed to be Celtic. The Celtic word for "blackbird", which served as the source for Latin, is uncertain and has various proposed forms, including "mēliros" or "mērlos". These theories suggest that the word "merle" has its roots in ancient Celtic languages.
Over time, the term expanded beyond its avian meaning and became associated with the color black. In certain contexts, "merle" can also refer to a dark-colored dog coat or a pattern characterized by irregular spots or patches of color.
