With an observed flux of $i_{\\rm AB}=23.0$, J141446.82+544631.9 is one of the brightest galaxies known at $z>5$. It is characterized by strong Ly$\\alpha$ emission, reaching a peak in (observed) flux density of $>10^{-16}~{\\rm erg}~{\\rm s}^{-1}~{\\rm cm}^{-2}~{\\rm \\AA}^{-1}$. A deep optical spectrum from the LBT places strong constraints on NV and CIV emission, disfavouring an AGN source for the emission.
