Translating multiword terms can pose problems at different levels. First, they need to be correctly identified and understood in the source text with a view to translating them. However, the answer to these questions cannot always be found in terminological resources such as dictionaries or databases. Therefore, translators must use other information-rich resources such as corpora. In order to make the most of them, the diverse corpus query techniques available in current corpus analysis tools must be mastered. However, these techniques are often unknown, which results in the reluctance of many translators to use corpora (Bowker 2004; Gallego-Hernández 2015; Loock 2016). This paper presents a step-by-step protocol that facilitates the comprehension and translation of multiword terms by means of parallel and comparable corpora. The procedure is illustrated with English multiword terms, which are translated into French and Spanish.
