The legal significs and semioethics methodology adopted in this book constitutes a valuable tool to interpret the content of international human rights treaties. This method has allowed for a demonstration that the terminology employed to identify the girl child in international law (sense) is carefully pondered by the drafters of treaties (meaning-intention), and considerably impacts the conceptions of girlhood globally as well as girls’ rights and their implementation at the domestic level (significance). Our analysis has underscored that the first obstacle to the protection of the girl child lies in the silence concerning the boundaries and divisions of girlhood and womanhood internationally. The terminology employed in international human rights treaties is insufficient to clearly identify the girl child and protect her rights.
