Si exista en Español y inglés, son artículos definidos ( el, la, los, las ) y artículos indefinidos ( un, una, unos, unas )
Yes, they exist in Spanish and English, as indefinite articles ( a, an ) and definite articles, which English has one ( the )
Japanese does not to my knowledge have any articles, これは何 could mean what is this or what are these. りんご could be one or more apples.
