For instance, we have in the bilingual dictionary that "tomàquet" is
"tomato", but if in the text we have one of the many possibilities for
"tomato" in Catalan, and we do not have added it in the bilingual
dictionary, "tomàtiga", "domàtiga", "tomata", etc. could be translated into
"tomato" if someone has not added all of them into the bilingual dictionary
(as usually nobody does). The same is for low-frequence synonyms, e.g.
old-fashioned, etc. (Spanish "congratular" for "felicitar", Catalan
"maridar" for "casar", etc.).
