But samma is different, because the "base noun" doesn't take definite form, while it does with "hela", right?
Indeed! Samma never describes a definite, while hela might or might not, but never takes den/det.
Thanks, your reply made me correct a mistake I made. "Hela" never takes den/det with a definite, but it can describe one.
Does hela mean something different that hel? I don't understand why it's not "hel" here.
With a definite noun, the adjective takes the plural form. Typically the definite article is required as well, but based on the comments above hela and samma are exceptions on this front.
Edit (from the adjective hints):
If the noun is definite, the adjective takes the ending -a in all cases, no matter gender or number. What’s important to note, however, is that whenever a definite noun is used together with an adjective, an article is placed in front of the adjective. This article is den for singular en-words, det for singular ett-words, and de for plural words (note that de is pronounced as ‘dom’).
en stor fisk → den stora fisken ett gult bord → det gula bordet snälla hundar → de snälla hundarna
Is läser past tense and pre tense as read and read are? It would work either way in this sentence particularly.
Based on another sentence in the lesson, I tried "we study the whole report." Not accepted. :-(
