The goal of this paper is to suggest a feature-based analysis for the licensing of null subjects found in languages. After reviewing the uniformity principle suggested in 1980s, we investigate the possibility of more insightful description on the distribution of null subjects based on Holmberg and Roberts (2013)'s research. Then we show that the typological classification of the null subject constructions among languages helps to provide a universal rule that applies to explain the full, partial and radical pro-drop phenomena among languages. Finally we suggest a feature copying or feature sharing analysis for null topic and null subject constructions in Korean.
