In this paper we analyse some 600 recent names of various firms in Łódź and the Łódź region. The analysis concentrates on problems of language correctness and functionalism. The criteria of correctness used in our paper were formulated in 1937 by Zenon Klemensiewicz, according to whom a name of a firm should briefly inform about the firm’s activity, should be concise, easily understood, formed in agreement with rules and tendencies of contemporary Polish, and original. We devote special attention to loan elements at different levels of linguistic analysis: lexical, morphological, phonetic, graphic, and to the so called disintegrating compounds and acronyms, with constitute the most frequent structures in the analysed material.
