What's more correct: on an as needed basis or as needed basis?
That makes sense. Are there any other phrases or sayings that people often get wrong in terms of grammar or correctness?
There are many, but one common mistake people make is using "less" instead of "fewer." "Less" is used to refer to things that cannot be counted, while "fewer" is used for things that can be counted. For example, it should be "fewer people" instead of "less people."
