"How do I pronounce 'now'?" is a question about the correct English pronunciation of the word "now." The correct pronunciation is /naʊ/, with a long "o" sound and no vowel before or after it.
To say "now," you should place your mouth in the shape of an O and make the sound as if you are saying the word "no." Keep your tongue close to the roof of your mouth and your lips relaxed. You can also try saying "noo-ow" if that helps you get the correct sounds.
It's important to practice pronouncing words correctly, especially when speaking with others. By improving your pronunciation, you can better communicate and understand English speakers from all over the world.
