In multidisciplinary communication, putting standardised lexicons into practice is essential in order to avoid problems such as terminological misinterpretations and ambiguity. Most standardised lexicons take English as a basis; however, in many cases Romance languages are not taken into account. In this work, lexicons for manufactured objects are presented in the main Romance languages (French, Italian, Spanish, Portuguese, Romanian, and Catalan) together with the seminal English lexicon. This multilingual lexicon is organised in the style of a traditional dictionary. It concerns either past or present, original or (contemporary or not) copied items, and is intended to help people active in any field in which manufactured objects may be involved, from museum pieces to factory-made items.
