Questions & Answers about Morgen is het de vierde mei.
Why is it is het instead of het is?
Because the sentence starts with the time word Morgen (Tomorrow). In Dutch, when you put a word that isn't the subject at the beginning of the sentence, the verb and subject swap places. So het is becomes is het. This rule is called inversion.
Why do we need the word het here?
Here, het means "it". Just like in English, Dutch uses "it" as a placeholder subject to talk about time, dates, and the weather. For example, "it is raining" or "it is the fourth of May".
How does vier (four) become vierde (fourth)?
To make an ordinal number (like fourth, fifth, or sixth) in Dutch, you usually add -de to the end of the number. So vier becomes vierde. Keep in mind that 1st (eerste), 3rd (derde), and 8th (achtste) are irregular!
Why isn't mei (May) capitalized?
Unlike English, Dutch does not capitalize the names of months, days of the week, or seasons.
