But you can also say ‘checks’ or ‘checks out’ in English for that. In fact, I'd usually prefer that to ‘matches’ in the singular with no direct object. (With a direct object, it's ‘The name matches the other name.’, which is different from how ‘checks’ works with a direct object; in the plural, it's ‘The names match.’, with an implied direct object ‘each other’.)
I'd use plural if there is no further context. "O nome confere" appears to be an incomplete sentence and missing an object. DL often has incomplete sentences though ... it's funny to imagine the scenarios sometimes. :D
Based on molypanchita's answer, I was imaging it as a response to something said before. For example, an investigation by two detectives about somebody, then a discussion between them in a movie. :D
Without knowing the circumstances, this seems strange, but sometimes this sentence does make sense. If a person were to show up at a voting location, for instance, the poll workers would have a list of registered voters. They then would ask for the voter's name and check the list. Therefore if the name is on the list, they may say that the name matches one on the list
"The name checks" doesn't mean anything in English. No sign of "matches" anywhere in the clue. Thanks DL for such rubbish clues!!!! When you introduce a new word, it would be wonderful if you provided a proper range of meanings and an explanation as to what it means in the given sentence.
