This paper describes an experiment to evaluate the impact of idioms on Statis- tical Machine Translation (SMT) process using the language pair English/Brazilian- Portuguese. Our results show that on sen- tences containing idioms a standard SMT system achieves about half the BLEU score of the same system when applied to sentences that do not contain idioms. We also provide a short error analysis and out- line our planned work to overcome this limitation.
