Menardos then returned to Cyprus and worked as the principal of the Greek School at Larnaca (Ελληνική Σχολή Λάρνακος) between 1896-1898.

He wrote studies on linguistics, toponymy, folklore, mostly about Cyprus, but also Lesbos, Rhodes, Cephalonia, Tinos and Mykonos.

[7] He published a number of books as well as articles in journals such as Δελτίον Ἰστορικῆς καί Ἐθνολογικῆς Ἑταιρείας, Αθήνα, Νέος Ἑλληνομνήμων, Λαογραφία, Ἐπετηρίς Παρνασσοῦ.

[8] Menardos was appointed to the first Lectureship in Mediaeval and Modern Greek at Oxford University, giving his inaugural lecture on 29 October 1908.

In 1919 he inaugurated the Koraes Chair at King's College, with a series of lectures on modern greek poetry.

[14] In honour of his contributions to the study of the Cypriot dialect, the Cyprus University of Technology has named its language center after Menardos.
