While etymology deals with the origin and meaning of words and their history, including the history of their change in meaning, onomasiology and semasiology investigate the language-internal relationships between words and meanings. Onomasiology examines the designation and the change of designation of objects by words depending on diverse contexts. In contrast, semasiology investigates how words can have different meanings depending on different contexts. As onomasiology deals with word formation and word creation, semasiology explores the possibility of creating new meanings through new assignments of words and contexts. Semasiology thus has something magical about it. Words become a kind of incantation to make the world reveal itself.
