Taxonomy ''Arachnothryx'' was named by Jules Émile Planchon in 1849.''Arachnothryx'' In: International Plant Names Index. (see ''External links'' below).Jules Émile Planchon. 1849.

It is a subfield of historical linguistics, and draws upon comparative semantics, Morphology_(linguistics), morphology, semiotics, and phonetics. For languages with a long recorded history, written history, etymologists make use of texts, and texts about the language, to gather knowledge about how words were used during earlier periods, how they developed in Semantics, meaning and Phonological change, form, or when and how they Loanword, entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct information about forms that are too old for any direct information to be available. By analyzing related ...
