What’s the meaning of the usage ‘untill otherwise’? Pls suggest a few examples.
“Until otherwise” would need to be accompanied by some verb in order to be precisely defined. You have given us a conjunction and an adverb. All I can say is that it means some action is expected to happen up to the point that something contrary occurs.
Until instructed otherwise, write in blue ink only. - Write in blue ink up to that point that you are told you can use something else.
