Stellar equivalent widths and hydrogen line profiles measured from a high quality coudé spectrum, are used to determine accurate atmospheric parameters for the early-type halo star HD 214080. Abundances of helium plus eleven other species are also derived, and are found to be similar to those of normal OB stars, from which it is concluded that HD 214080 is an ordinary Population I object. The stellar velocity coupled with its z-distance imply that HD 214080 cannot have been ejected from the disc as has been proposed for other halo stars. It is concluded that the star was probably formed in the halo, possibly as a result of cloud-cloud collisions at high galactic latitudes.
