The article deals with the of terms with international components in Ukrainian language. The essence of the term 'codification' and its connections with the concepts of 'standardization' and 'normalization' have been found out.

Common for these meanings the written fixation, which is of a recommending nature. Standardization means that only one term must survive, and any other is deleted. Normalization pertains the process in any terminology that happens on two levels: lexical and word-building. The essence of codification is the objective assessment of language doublets, variants, innovations, trends of development. Codification can be absolute and relative. Absolute is related to the established norm, since the use of many words and terms with the MC does not cause any warnings. These words got into the language, became theirs own, without them we cannot provide our daily and scientific communication. Relative is associated with tensile shaky norm. Actually, it requires a careful attitude towards invariants and variants in favor of one in them.
