contribute
/kənˈtrɪbjuːt/·컨트리뷰트·verb
to give jointly toward a goal
LatinCEFR B1
Root
con- (together) + Latin 'tribuere' (to give)
Latin contribuere → Middle English contribute → Modern contribute
In a word
con- (together) + tribute (give) = 'give together'. No one person has to give everything — gather a little from each, and it's contribute. Open-source "contributor" carries the same root — people putting code in together. The etymology quietly says: you don't have to carry it alone.
Examples
Everyone contributed to the project.
I contribute a small amount each month.
Volunteers contributed their time.
