Anxious is a word that is often mispronounced. To correctly pronounce anxious, begin by saying the first syllable with a short "a" sound, similar to the sound in the word "cat." Then, say the second syllable with the "ng" sound, as if you are humming. Finally, end with the "shuhs" sound, similar to the sound in the word "push." All together, anxious should sound like "an-g-shuhs."
Practice saying anxious aloud a few times to make sure you have the sound right. If you're having difficulty, record yourself saying it and then play it back to hear how it should sound. With enough practice, you'll soon be able to confidently and correctly pronounce anxious.
