Consider the example sentence in the cropped graphic above. The untrained writer may not see a problem here. But there is a problem. The writer here used the hyphenated expression all-around, which as we just learned means comprehensive or versatile. That means we could replace the word the writer used with one of these synonyms and see if it makes sense.
The molten metal then flows versatile the ceramic core.
So get all around the hyphen in all-around, and be that more effective writer. Increasing your precision of language will help you communicate more effectively with your intended audience. And a more effective presentation means an improved image of your professional brand in the minds of your audience.
