rill
UK[rɪl]US[rɪl]
n
A very small, narrow stream or channel, especially one formed by running water.
Etymology
The word 'rill' entered English in the 16th century, borrowed from the Dutch 'ril' or Low German 'rille', meaning a furrow or small stream. These Germanic terms are likely related to the Middle Low German 'rinne', meaning a channel or watercourse, which itself traces back to the Proto-Germanic rinnaną, meaning "to run" or "to flow." This etymological journey connects the core concept of flowing motion to the resulting physical feature, evolving from a general verb for movement into a specific noun for a tiny, flowing stream carved into the earth.
Analysis
This word is a simplex form. It is a loanword from Dutch or Low German, where 'ril' or 'rille' refers to a groove or channel. Its functional role is as a complete lexical root.
