Etymology The way how a word comes. The essential language learning tool. When you want to study the origin of a word or learn the way in which its meanings have been changed throughout history, a serious and professional etymology English dictionary is very useful for rapidly searching accurate references. Knowing the origin of a word and the historical development of its meaning is an important part of language learning. This dictionary has collected a large number of sources, including variant of dictionary, lexicon, encyclopaedia, dialect, argot, jargon, slang, place name, surname, chemical name, music, linguistic data, ancient poems and books, the relations between different languages and other valuable materials, and be crafted as a practical pocket tool. Features: * Not only indexed etymologies by a word, but also words that have the same root indexed too. * List the language family, the nationality or the dialect area of the source. * Cross references of all root and keyword, search whole dictionary by only one link. * Add or remove your favourite to bookmark and conveniently review them later.
