ríðill
Ríðill is an Icelandic word that primarily refers to a brook or stream. It is a masculine noun. The word is often used in a descriptive sense, denoting a small, flowing body of water, typically one that is less substantial than a river (á). The term can appear in place names throughout Iceland, indicating the presence of such water features in those locations. For instance, a farm or a valley might be named Ríðill if a brook runs through or near it. The etymology of the word is believed to be related to the verb "ríða," meaning to ride or flow, suggesting the movement of water. While "ríðill" is the most common translation, depending on context, it can sometimes be understood more broadly as any small watercourse. The usage of "ríðill" is specific to the Icelandic language and its cultural landscape.
