Quick summary: You should say "correction(s) to" when describing tangible, countable changes, but "correction of" when describing the general act of correcting, but no one is likely to care if you mix it up.

Right away, we can rule out "corrections with." This has a different meaning: "with" introduces an object which is doing or aiding the corrections. For example, we can say "I made corrections with a pen," but should not say "I made corrections with spelling" (although this would still be easily understood).

The other choices are a little murkier. I've encountered "corrections of...", "corrections to..." and "corrections in..." in well-written literature. To my ear, "corrections to..." sounds the most correct, but not by much. Since English has no authoritative definition, we have to do a little more research.

First, we have to make a distinction between two subtly different meanings of "correction." The first meaning refers to the change itself. From dictionary.com:

noun 1 something that is substituted or proposed for what is wrong or inaccurate; emendation.

We intend this meaning when we talk about making a correction. It is a countable noun: you can make 2 or 3 corrections, for example.

The second meaning refers to the action of making the change:

noun 2 the act of correcting.

We intend this meaning when we talk about the general act of correction. It is an uncountable noun. For example, "vitamins can be prescribed for correction of nutrient deficiency."

In the OP sentence, the first meaning (1) is the sense intended.

Here are some example sentences listed at dictionary.com and Merriam-Webster. In each example I have marked which of the two above meanings (1 or 2) are being used, and I have also emphasized the preposition following correction in bold.

  • dictionary.com:

    • He ordered his secretary to reimburse the fees and will issue a correction to his political funds reports. (1)
    • Cases may arise in which a correction of the judgment thus formed may be necessary. (2)
  • Merriam-Webster:

    • correction of (acidity / vision / etc.) (2)
    • Restylane® Silk is for lip augmentation and for correction of perioral wrinkles in patients over the age of 21. (2)

We can also look at Ngrams, although we have to be careful to note that Google's search engine is not capable of differentiating between meanings 1 and 2 that we distinguished earlier.

corrections to/of/in: Ngrams for corrections X

correction to/of/in: Ngrams for correction X

The top graph uses the plural corrections, which limits the results to the countable form (meaning 1). It clearly shows that to is the preferred preposition.

The bottom graph uses the singular form correction, which would include both meanings 1 and 2. It clearly shows that of is the preferred preposition.

Taking all of this into account, it seems safe to infer that when speaking about tangible, countable corrections being made to something, the preferred form is corrections to:

I made corrections to the spelling and grammar.

On the other hand, when talking about the general, uncountable act of correcting, the preferred form is corrections of:

Vitamins can be prescribed for correction of nutrient deficiency.

Of course, I doubt many native speakers have ever taken the time to think about this, and I seriously doubt very many people would think twice whether you say "to," "in" or "of."


Between your two example sentences both are understandable, but

require a lot of corrections with grammar and spelling.

would probably be the more common usage. "A lot" implies many therefore plural corrrections.

These are the corrections with your grammar and spelling.
These are the corrections on your grammar and spelling.

  • Thanks a lot Peter.Just one clarification.. What if I meant correction as a verb rather than a noun? i.e. lot of correction to be done by the teacher and not the actual corrections (mistakes).

    An Ngram comparison shows that correction/s of is vastly more popular than correction on/with. Apr 23, 2017 at 22:25
  • I might say that it should be that they "require a lot of corrections of grammar and spelling", if this way of wording it is preferred. Aug 11, 2017 at 22:21
  • @AanchalS That's not a verb (the verb is "correct"), that's an uncountable noun. Apr 24, 2019 at 16:32

I would suggest the correct answer is in fact this:

He has started constructing meaningful sentences which require a lot of corrections to grammar and spelling.

Spelling should be singular even when referring to multiple instances of correction. Correction or corrections I don't think makes a lot of difference and works either way, corrections feels a little more natural to me.


"grammar and spelling[s]" describe what "correction" consists of, so it would "of".
