According to one article reference book, it says we can omit articles (a, an, the) in front of the second, third,… nouns. Is it really acceptable from native English speakers' point of view? Is it really grammatically correct and allowed in writing? The book says it is so clear that each item (noun) is a different item, so we do not need to repeat the article.
I bought a lemon, melon, and pineapple.
I asked her to pass me the pen, eraser, and pencil sharpener.
I understand we can definitely place "a" in front of each noun, but could placing the articles (a, the) be redundant?
