Iterate

"Reiterate" is really a redundancy. Iterate means to "to say or perform again." Unless you actually mean "to repeat again," then saying "re-iterate" is unnecessary.

Many dictionaries are now listing both of these words. The form ‘reiterate’ is most commonly heard in everyday speech, but crept into the language through what’s known as hypercorrection: correcting something which is already right.

‘Iterate’, on its own, already means ‘to say or perform again/repeat something’. However, many people do not know this, so they add ‘re’ to the word, thinking that this will give the ‘again’ element.

Example:

• ‘He iterated his point.’ NOT ‘He reiterated his point.’

So, you would use ‘reiterate’ only if you actually were iterating again, for a second/third time!
