Historical Lexicology deals with evolution of the vocabulary units of a language as time goes by.

Contrastive and Comparative Lexicology deal with the study of the correlation between the vocabularies of two or more languages, finding out the correspondences and differences between the vocabulary units of the languages under comparison.

Morphology is the branch of Lexicology studying the structure of a word, types of morphemes and stems.
Semasiology is the branch of Lexicology that is devoted to the study of meaning of lexical
units.
Phraseology is the branch of Lexicology specializing in the phraseological subsystem of
language and is concerned with all types of set expressions.
Lexicography is the science of dictionary-compiling dealing with the problems of the presentation of the number, forms, meaning, usage and origin of vocabulary units.
Etymology is the science studying the origin of the words, native and borrowed lexical units, ways of the assimilation of borrowed words, external replenishment of the vocabulary.

Morphological structure of the word
Morpheme is the smallest two-facet unit (it has sound form and meaning) to be found within the word which is studied on the morphological level of analysis.
All morphemes are subdivided into two large classes: root (free) morphemes and non-root (bound) morphemes. Bound morphemes are represented by grammatical (inflections) and derivational (affixes) morphemes. Affixes include suffixes, prefixes, infixes and semi-affixes.
Semantic features – root morphemes (have individual lexical meaning) and non-root morphemes (have generalized meaning).
