"Descoperirea lui a schimbat vechile concluzii."

Translation: His discovery changed the old conclusions.

[Monica684041]

starting from the expression "old conclusions" ...
with its equivalent in Romanian " vechi concluzii " or "concluzii vechi "

when you want to stress such an expression by using the definite article ( "the old conclusions" ),
you have in Romanian two possibilities to say that :

1) vechi-le concluzii

2) concluzii-le vechi

......
it means ...

you put the plural ending "-le" for the definite article either to the adjective or to the noun ,
but only to the first of them in the expression ...

not to both of them like for ex. in French ...

[LouisSepdekdu]

In French, you put the article in front of them and only once. "Les vieilles les conclusions" is really bad French.
