For a liquid advancing or receding on a flat bare solid in a vapor atmosphere, we show that no singularities in
fact arise at the contact (triple) line. Contrary to common expectations, this does not require any “regularizing”
microscopic effect (such as slip at the substrate, disjoining pressure or precursor films). The key here is the
Kelvin effect, i.e., a curvature-induced variation of saturation conditions. Importantly, no evaporation-related
singularities appear either. We proceed within the lubrication approximation and a classical one-sided model for
zero or finite contact angle.
