Common Mistakes - By or Until
Until tells us how long a situation continues. If something happens until a particular time, you stop doing it at that time. (Until nos fala sobre a duração de alguma atividade. Se algo acontece "until" um tempoo em especifico, significa que você irá parar naquela data). For example: They lived in a small house until September 2003. (They stopped living there in September.) I will be away until Wednesday. (I will be back on Wednesday.) We also use until in negative sentences. (Usado também nas sentenças negativas) For example: Details will not be available until January. (January is the earliest you can expect to receive the details.) If something happens by a particular time, it happens at or before that time. It is often used to indicate a deadline.(Se algo acontece "by!" um tempo especifico, acontecerá neste tempo ou antes. É sempre usado para um indicar uma linha de tempo)...
