The correct tone of 一杯


#1

Hi @YuQinCai, @Constance_Fang @Fiona and the ChinesePod team, my question is this:

When you say “一杯”,the tone is yi1 bei1, or yi4 bei1?
Thank you!

Great question! The 一 turns into a 4th tone when it comes before another 1st tone. So it’s yì bēi. In terms of writing the Pinyin, it’s correct either way.

There’s an Elementary lesson on this is you want some more review and see some of the other tone change rules.
