Learn Dutch: Ik haat vlees.

You would say Ik haat vlees niet. When using niet (not) to negate a verb like haat, it typically goes at the end of the sentence, after the object (vlees).

Why does haat have two a's when the full verb is haten?

When we drop the -en from the full verb haten to make the 'I' form, we are left with hat. In Dutch spelling, a single vowel followed by a single consonant at the end of a word is pronounced short. To keep the long 'a' sound of the original verb, we have to double the vowel, making it haat.

Why is there no article like het before vlees?

Just like in English, Dutch leaves out articles when talking about uncountable nouns in a broad, general sense. You are talking about meat in general, so no article is needed. If you said Ik haat het vlees, it would mean you hate the specific meat in front of you.

How do you pronounce vlees? Does it sound like the English word 'fleece'?

Not quite! The Dutch v at the start of a word is often pronounced very softly, almost like an English 'f'. However, the double ee makes a long 'ay' sound, similar to the 'a' in 'face'. So vlees actually sounds closer to the English word 'flays'.
