How did the us contribute to ww1 prior to entering?

Before officially entering World War I in 1917, the U.S. contributed to the war effort by providing financial support and supplies to the Allies, especially Britain and France. American banks and businesses extended loans and sold war materials, which helped sustain the Allied powers. Additionally, the U.S. maintained a strong trade relationship with these countries, supplying food, munitions, and other essential goods while remaining neutral in the conflict. This economic involvement created a significant stake in the outcome of the war.
