New vocabulary is generally created through an analysis of the word, its etymology, and reference to the six source languages. If a word can be created through vocabulary already existing in the language then it will usually be adopted without need for a new radical (such as wikipedio for "Wikipedia", which consists of wiki + enciklopedio for "encyclopedia"), and if not an entirely new word will be created. The word alternatoro for example was adopted in 1926, likely because five of the six source languages used largely the same orthography for the word, and because it was long enough to avoid being mistaken for other words in the existing vocabulary. Adoption of a word is done through consensus, after which the word will be made official by the union. Care must also be taken to avoid homonyms if possible, and usually a new word undergoes some discussion before being adopted. Foreign words that have a restricted sense and are not likely to be used in everyday life (such as the word "intifada" to refer to the conflict between Israel and Palestine) are left untouched, and often written in italics.
