Expert writing Tips
Best practice
Use the correct preposition "by" instead of "from" when indicating what something is being replaced with. For example, "The old system will "to be replaced from" the new software" should be "The old system will be replaced by the new software."
Common error
Avoid using "from" after "replaced"; the correct preposition is "by" to indicate the replacement. Saying "replaced from" is grammatically incorrect and sounds awkward.
