===Pronunciation===
* {{sense|number|digit|“zero”}}
** {{enPR|zē′rō|a=Aus,US}}, {{IPA|en|/ˈziːɹəʊ/}}
** {{IPA|en|/ˈzɪəɹəʊ/|a=RP}}
** {{audio|en|en-us-zero.ogg|a=US}}
** {{rhymes|en|ɪəɹəʊ|s=2}}
* {{sense|digit|“[[nought]]”}}
** {{IPA|en|/ˈnɔːt/|a=RP}}

* {{sense|digit|“oh” [[o]]}}
** {{IPA|en|/ˈəʊ/|a=RP}}
** {{rhymes|en|əʊ|s=1}}
*: The pronunciation as a [[digit]] is very often shortened to that of the letter {{m|en|o|O}} to save time or keep rhythm. This change is required for the [[tens place]] of [[minute]]s following the [[hour]] and in shortened pronunciation of numbers between 10 and 19 hundred, including [[year]]s, as well as their truncated two-digit forms, where the zero is a leading digit. It is also very common when saying [[telephone number]]s, [[decimals]] after the [[decimal point]], the [[leading zero]] in decimal fractions less than one, or many other words such as {{m|en|007}} ''double o seven''.
