I think good grammar is important and attractive! As a VA, it is part of my job to notice grammar, spelling and the proper use of words. Common mistakes can do serious damage to an otherwise stellar reputation. Think about the image you project and proofread, do some research, look it up…or ask me!
Momentarily
Momentarily can have two meanings: (1) in a moment, or (2) for a moment.
Examples:
1. The food will be served momentarily.
2. The meeting will adjourn momentarily.
Often the context will make it clear which meaning is intended (clearly food is not going to be served for just a moment), but sometimes the meaning can be ambiguous. In looking at the second example above, one might question whether the meeting will adjourn for a moment or in a moment. To avoid confusion, be sure that your intended meaning is clear from the context, or simply substitute momentarily with “in a moment” or “for a moment.”
