The Maltese place-name Għadira aˈdiːra is almost universally explained as a reflex of Arabicﻏَﺪِﻳﺮ (ġadīr: pond, pool, or small stream). While this interpretation is semantically plausible, the documentary record itself has received surprisingly little attention. This study is therefore concerned less with proposing a new etymology than with reconstructing the documentary history upon which any future etymological discussion must necessarily rest. Medieval and early modern sources repeatedly preserve the form Gadir, rather than the later normalised spellings Għadir1 or Għadira. This note reconstructs the documentary history of the toponym from the fifteenth to the seventeenth century through the Militia roster (1417), the Menqa de Gadir document (1522), the notarial act of 1530 referring to stagni appellati Gadir, subsequent sixteenth-century references, and Giacomo de Rossi's map of Malta (1686), which records La Mad. di Gadir Bordi. Rather than proposing a definitive etymology, the paper argues that the documentary history of the name deserves reconstruction before competing linguistic explanations are evaluated. The discussion concludes by situating the Maltese evidence within a broader Mediterranean context while recognising the orthographic fluidity characteristic of pre-standard Maltese. 1 Throughout this paper, Gadir refers to the historical documentary spelling preserved in medieval and early modern sources, whereas Għadir and Għadira designate the corresponding modern standardised Maltese forms. The modern Maltese digraph għ represents the historical reflex of the Arabic consonant ghayn (غ), although in contemporary Standard Maltese it is no longer generally realised as an independent consonantal segment, instead influencing the quality, length, and stress of adjacent vowels. Consequently, the distinction between the documentary form Gadir and the modern spelling Għadir is primarily orthographic and historical rather than a direct reflection of contemporary pronunciation.
