Why it cannot be "Het jongens eten rijst" ? Thank you for explaining the difference between "Het" and "De" for "the".
You always use "de" with plural.
From what I understand so far I think "eten" is when you're talking about more than one person doing it... it is a plural form of eating.
De jongens eten jullie - well then.
What about eet? Cant we use eet instead of eten?
No. When you conjugate verbs for plural nouns, you always use the infinitive form. For eten specifically*, "eet" is for all singular nouns and "eten" is for all plural nouns.
*Many other verbs have a bit more conjugation for the singular nouns.
