Expert writing Tips

Best practice

Use "reduce" without the preposition "on" to express the act of making something smaller or less. For example, "We need to reduce our expenses" is correct.

Common error

Do not add the preposition "on" after "reduce". The correct form is simply "reduce", followed by the object you are lessening. "Reduce on expenses" is incorrect; instead, say "reduce expenses".

Ludwig's WRAP-UP

In summary, the phrase "reduce on" is grammatically incorrect in standard English. Ludwig AI confirms this, stating that the correct form is simply "reduce" without the preposition "on". While the intention may be to express a lessening or decrease, the non-standard usage undermines clarity. It's essential to avoid "reduce on" in both formal and informal contexts, opting instead for "reduce" or semantically similar alternatives like "decrease", "lower", or "cut down".

FAQs

How do I properly use the word "reduce" in a sentence?

Use "reduce" followed directly by the noun you want to lessen. For instance, say "reduce costs" or "reduce waste", not "reduce on costs" or "reduce on waste".

What is a common mistake people make when using "reduce"?

A frequent error is adding the preposition "on" after "reduce". Remember that "reduce" is a transitive verb that doesn't require a preposition in this context.

Which is the correct phrase to use, "reduce costs" or "reduce on costs"?

"Reduce costs" is the correct and standard way to express lessening expenses. "Reduce on costs" is grammatically incorrect. Consider alternatives like "cut down on costs" if you want to use a preposition.

Are there any situations where I would use "on" after "reduce"?

While "reduce on" is generally incorrect, "reduce" can be followed by "to" or other prepositions in different contexts. For example, "reduce something to ashes" or "reduce someone to tears" are valid uses, but they have different meanings than simply lessening something.
