The phrase "at the same time" is used to indicate that two or more things are happening concurrently or in unison. Here are some synonyms and an analysis of them:
1. Simultaneously
- "Simultaneously" is a very close synonym to "at the same time." It emphasizes the exact coincidence of events in time. For example, "The two rockets were launched simultaneously." It gives a precise sense that the actions are happening at precisely the same moment without any delay between them. This word is often used in technical, scientific, or formal contexts where the exact timing of concurrent events is important.
2. Concurrent(ly)
- "Concurrent" as an adjective (and "concurrently" as an adverb) means happening at the same time or overlapping in time. For example, "There were concurrent meetings in different rooms." The difference between "concurrent" and "simultaneous" is that "concurrent" can imply a broader sense of happening during the same period, not necessarily at the exact same instant. It allows for a bit more flexibility in the timing, suggesting that the events might overlap or run parallel to each other for a while.
3. At once
- "At once" can also mean at the same time, but it has a slightly different nuance. For example, "He tried to do two things at once." It implies a sense of immediacy and a bit of a hurried attempt to perform multiple actions together. It's a more casual and perhaps less precise way of expressing the idea of simultaneity compared to "simultaneously."
4. In unison
- "In unison" means in complete agreement or harmony, and when it comes to time, it implies that actions are coordinated and happening together. For example, "The dancers moved in unison." It's often used to describe actions that are not only happening at the same time but also in a coordinated and harmonious way. This phrase is more commonly used when there is a sense of cooperation or synchronization among different entities.
5. Co - incidentally
- "Co - incidentally" means happening by chance at the same time. For example, "Co - incidentally, they both arrived at the party at the same moment." It emphasizes the unexpected nature of the simultaneity, as if the two events just happened to occur together without prior planning.
