Following the decline of Manx as a community language on the Isle of Man during much of the 19th century, interest in the language was renewed, most notably among educated men in the town of
Peel where it was still common to hear Manx spoken by the fishermen. Although Clague was in the south of the island, there were still many native speakers; and by talking to them, he taught himself the Manx language as part of his effort to preserve traditional Manx culture. Along with several other prominent members of the Manx language revival such as
J. J. Kneen and
Edmund Goodwin, Clague was a founding member of
Yn Çheshaght Ghailckagh in 1899 in Peel.
A. W. Moore, the director of the
Manx Museum and the organisation's first president, explained that Yn Çheshaght Ghailckagh was concerned not only with the preservation and promotion of the Manx language, but rather with all things related to Manx culture:Though called the Manx Language Society, it should, I think, by no means confine its energies to the promotion of an interest in the language, but extend them to the study of Manx history, the collection of Manx music, ballads, carols, folklore, proverbs, place-names, including the old field names which are rapidly dying out in a word, to the preservation of everything that IS distinctively Manx, and, above all, to the cultivation of a national spirit. == Later years ==
