When typing a sentence, where should you not add spaces?

When typing a sentence, you should not add spaces before or after a slash. The slash is meant to connect ideas or represent options, and placing spaces around it disrupts its function and can lead to confusion.

In contrast, it is generally standard practice to have no space before a period, ensuring continuity with the preceding word, while adding a space after to clearly separate the ending of one sentence from the beginning of another. Similarly, commas should follow the same rule: no space before them, and a space should follow to maintain clarity in the sentence's flow. Between words is where spaces are necessary to separate distinct elements of the sentence for readability.
