Is a noun's article always necessary

[jrhjazznblues]

How weird does it sound to a Spanish speaking person if you say, for example, no bebemos durante almuerzo, instead of el almuerzo. Is it grammatically correct?

[aleCcowaN]

It sounds pretty Tarzanesque, or like a short note or a telegram "no beber durante almuerzo".

Are there any exceptions? The reason I ask is that Duolingo sometimes omits the article, and I wonder whether or not that is a mistake

[AngelicaDeAlquezar]

It depends on the context. Concrete situations like having lunch cannot be expressed without the article.
Can you quote the examples so we can try explaining why those articles were omitted? :)

There are certainly times when a definite article is not used.
And there are times when a definite article is needed in Spanish but omitted in English.

There are some good sites that provide some rules.
Have a look here (https://languageboat.com/2013/11/27/when-to-use-or-omit-definite-articles-in-spanish/).

Not sure how to tag people in posts, or if I even can, but @angelicadealquezar I don't remember any of the specific examples. @Rusty thank you very much!
