In Chinese, you can use 博士的博 to indicate the character 博 instead of other bó. Like a for apple or b for baby.
What about for the character 格, what do most Chinese people commonly use in practice to indicate / address the character 格 instead of other characters that represents the same sound gé?
Note I'm asking in the context of when someone is trying to spell a word to another person that is writing what he listening to. And that word coincidentally contains the character 博. Using what word would you address it since the characater 博 doesn't have an official name of its own in chinese.
