The surname Pallara shows a nickname origin with different possible interpretations. In this sense, F. De Laurentiis notes that it may derive from nicknames formed from the Latin term palla ("feminine garment"), applied in specific social contexts, in particular to allude to women who were not joined by a formal matrimonial bond.

For his part, E. Rossoni proposes different alternatives, linking it either with place names or with the medieval Latin term pallarus ("hayloft"), which could indicate a reference to the environment or to rural activities. In this way, the surname could reflect both a nickname of a social character and a designation related to the place of residence or the sphere of work, without a single definitive interpretation.
