It is well known that nominalization represents a component part of a wider linguistic phenomenon, named conversion, and consists in passing of a word from a certain part of speech to that of the noun. Lately, in the act of speaking, there is an intensification of the nominalization process of the adjectives. The fact is caused by the frequent, regular use of the adjective in a close syntactic connection with the noun. Consequently, occurs the compression, the restriction of the syntactic group (noun + adjective), the adjective assuming the meaning of the whole combination. Simultaneously, from a semantic perspective, it becomes more independent, fulfilling in the sentence the syntactic function of subject or complement. The process is so active, so that it also requires a lexicographical re-approach.
