      abstract     = {A search for the leptonic charge asymmetry ($A_{c}^{\ell}$)
                      of top-quark-antiquark pair production in association with a
                      $W$ boson ($t\bar{t}W$) is presented. The search is
                      performed using final states with exactly three charged
                      light leptons (electrons or muons) and is based on $\sqrt{s}
                      = 13$ TeV proton-proton collision data collected with the
                      ATLAS detector at the Large Hadron Collider at CERN during
                      the years 2015-2018, corresponding to an integrated
                      luminosity of 139 fb$^{-1}$. A profile-likelihood fit to the
                      event yields in multiple regions corresponding to positive
                      and negative differences between the pseudorapidities of the
                      charged leptons from top-quark and top-antiquark decays is
                      used to extract the charge asymmetry. At reconstructed
                      level, the asymmetry is found to be $-0.123 \pm 0.136$
                      (stat.) $\pm \, 0.051$ (syst.). An unfolding procedure is
                      applied to convert the result at reconstructed level into a
                      charge-asymmetry value in a fiducial volume at particle
                      level with the result of $-0.112 \pm 0.170$ (stat.) $\pm \,
                      0.055$ (syst.). The Standard Model expectations for these
                      two observables are calculated using Monte Carlo simulations
                      with next-to-leading order plus parton shower precision in
                      quantum chromodynamics and including next-to-leading order
                      electroweak corrections. They are $-0.084 \,
                      ^{+0.005}_{-0.003}$ (scale) $\pm\, 0.006$ (MC stat.) and
                      $-0.063 \, ^{+0.007}_{-0.004}$ (scale) $\pm\, 0.004$ (MC
                      stat.), respectively.},
