"Provided That" or "Providing That"?

Should I Write "Provided That" or "Providing That"?

"Provided that" and "providing that" are interchangeable when used to mean "on condition that." However, "provided that" is strongly preferred over "providing that" in the US and the UK.

Here are some examples:
  • Provided that the weather is fine, we'll have a picnic on Saturday. correct tick
  • Providing that the weather is fine, we'll have a picnic on Saturday. correct tick
  • (This is acceptable but is less common.)
  • Tony will attend provided that Sarah is not chairing the meeting. correct tick
  • The newspaper did not publish the photographs because they were given by a confidential source who did so provided that we not release them before the elections. correct tick
provided or providing
"Provided" is more popular than "providing." [evidence]

"Provided That" or Just "Provided"?

The word "that" can be omitted from both "provided that" and "providing that." For example:
  • Provided the weather is fine, we'll have a picnic on Saturday. correct tick
  • Providing the weather is fine, we'll have a picnic on Saturday. correct tick
Removing "that" is a good practice. Removing any word that doesn't add anything to your sentence is a good practice!

"Provided" Is More Formal Than "Providing"

Most writers maintain that "provided" is preferable to "providing" as a conjunction meaning "on condition that." Therefore, it is safer to choose "provided" or "provided that" in formal writing.
