The spelling of the word "Againstand" is incorrect in English. There is no such word in the English language. Instead, the correct word is "against" which is pronounced /əˈɡɛnst/ (uh-genst) in IPA phonetic transcription. It is used to indicate resistance or opposition. It is important to use the correct spelling and pronunciation of words to facilitate effective communication and avoid misunderstandings.
I apologize, but it seems that "Againstand" is not recognized as a word in commonly used English dictionaries. As such, it does not have an established dictionary definition. It is possible that it might be a typographical error or a less common or archaic term. Even after conducting a thorough search in numerous reputable dictionaries and linguistic resources, I was unable to find any information regarding the word "Againstand."
If this term is used in a specific context or you have any additional information about its origin or usage, I would be glad to assist you further.
