Here, we present optical and ultraviolet spectra of the first electromagnetic counterpart to a gravitational wave (GW) source, the binary neutron star merger GW170817. Spectra were obtained nightly between 1.5 and 9.5 days post-merger, using the SOAR and Magellan telescopes; the UV spectrum was obtained with the Hubble Space Telescope at 5.5 days. Our data reveal a rapidly-fading blue component ($$T\approx5500$$ K at 1.5 days) that quickly reddens; spectra later than $$\gtrsim 4.5$$ days peak beyond the optical regime. The spectra are mostly featureless, although we identify a possible weak emission line at $$\sim 7900$$ Å at $$t\lesssim 4.5$$ days. The colours, rapid evolution and featureless spectrum are consistent with a "blue" kilonova from polar ejecta comprised mainly of light $$r$$-process nuclei with atomic mass number $$A\lesssim 140$$. This indicates a sight-line within $$\theta_{\rm obs}\lesssim 45^{\circ}$$ of the orbital axis. Comparison to models suggests $$\sim0.03$$ M$$_\odot$$ of blue ejecta, with a velocity of $$\sim 0.3c$$. The required lanthanide fraction is $$\sim 10^{-4}$$, but this drops to $$<10^{-5}$$ in the outermost ejecta. The large velocities point to a dynamical origin, rather than a disk wind, for this blue component, suggesting that both binary constituents are neutron stars (as opposed to a binary consisting of a neutron star and a black hole). For dynamical ejecta, the high mass favors a small neutron star radius of $$\lesssim 12$$ km. This mass also supports the idea that neutron star mergers are a major contributor to $$r$$-process nucleosynthesis.
