I have been having difficulting using the word "accuracy" and I am not sure how to add an article before "accuracy". The sentence I am trying to write is "To guarantee accuracy, we ...".
I looked up in a dictionary and found that accuracy is countable. So I was told a countable singular-form noun should always have a leading article. However, another rule is that an article is not needed for abstract concepts. I believe accuracy is an abstract concept, so there should no article. So I am confused. Is that accuracy is both countable and uncountable and in this case we are using the uncountable version?
Here is a link to Merriam-Webster dictionary https://www.merriam-webster.com/dictionary/accuracy. It has a plural form, so I think that indicates "accuracy" is countable.
