Hi guys, <br/><br/>I'm writing an article and have found myself using "is is" in a sentence, the sentence is: <br/><br/>"All it is is a small container used for holding soil or water samples..." <br/><br/>It seems right hearing it, but on paper is a different story. <br/><br/>Just wondering if it is right to use it. I've tried other ways of expressing the sentence but none seem to click with what I'm writing. <br/><br/>Thanks for your help, <br/><br/>-Rage76
