Etymology is traditionally used for the study of the origins and history of the form and meaning of words.modern English is derived from the languages of early Germanic tribes with a fairly small vocabulary.we shall study how this small vocabulary has grown into a huge modern English vocabulary and explain the changes that have taken place in the forms and meanings of words.

Semantics is the study of meanings of different linguistic levels:lexis,syntax, utterance,discourse,etc.but lexicology will focus on the lexical level.The types of meaning and sense relations such as polysemy,homonymy,synonymy,antonymy,hyponymy and semantic field all belong to the scope of semantic study and constitute an important part of lexicology.
