Tributary
noun /ˈtrɪbjʊtri/ — A smaller stream that flows into a larger one — a contribution that becomes something bigger.
Definition
A river or stream flowing into a larger river or lake; also, a person or state that pays tribute to another.
Beyond the definition
A tributary's beauty is in its surrender — it gives itself to the larger river and is no longer separately named. The word works well as a metaphor for how smaller things feed larger movements: every tributary conversation feeding the main current of thought.
Origin & history
From Latin tributarius — paying tribute (from tribuere: to pay tribute, to distribute). What pays tribute — the smaller river offering itself to the greater. Hydrology as politics.
