If you're a non-native English speaker, you may have difficulty pronouncing the word "reiterate." Here's how to pronounce it correctly:
Say the word "reiterate" as if it were two separate words: "re-it-er-ate." Start by saying "re," like the first syllable in "repeat." Then say "it," like the word "it." Next, say "er," like the word "her." Finally, finish with "ate," like the word "plate."
When you combine these syllables, you should have "re-it-er-ate." The emphasis should go on the second syllable, so be sure to put a little extra emphasis on "it." It should sound like "REE-it-er-ate."
So, to reiterate: Say "re," like the first syllable of "repeat"; "it," like the word "it"; "er," like the word "her"; and "ate," like the word "plate." Put extra emphasis on the "it" syllable, and you should have "REE-it-er-ate."
