Sentence and word structure: Other interesting questions

What are some common compound words?: Some of the most common compound words include the following:

Compound nouns like “airplane,” “bookshelf,” “peanut butter,” and “watermelon”

All of the phrasal verbs (e.g., “hang out” and “dive in”)

The indefinite pronouns “everyone,” “someone,” and “anybody”

Compound adjectives like “old-fashioned”

Compound words can be closed (one word with no hyphen), open (two words), or hyphenated. When you’re writing with compound words, the Quillbot Grammar Checker will ensure that they’re spelled and formatted correctly.
Is it make sense or since?: It is make sense, not make since (e.g., “I don’t understand that sentence; it doesn’t make sense to me,” “Sure, I understand; that makes sense”).

The word since typically refers to the starting point of a time period that lasts up to the time of speaking (e.g., “I haven’t made peanut butter cookies since my kids were little”).

Quillbot’s free Grammar Checker will help you pick up typos like “since” instead of “sense” in your writing.
Is it affected by or effected by?: It can be affected by or effected by.

It is typically affected by, meaning “influenced by” (e.g., “The harvest was badly affected by the poor weather conditions”).

However, it can be “effected by” if you mean “initiated by,” “implemented by,” or “caused by” (e.g., “This was one of the positive changes effected by the organization”). The word effect is not commonly used as a verb like this in everyday language.

Quillbot’s free Grammar Checker will help you to avoid errors with commonly confused words like “affect” and “effect.”
Is it her and I or she and I?: “Her and I” is not correct, but you can use “she and I” because they’re both nominative case pronouns that can be part of a compound subject (e.g., “She and I lived together during college”).

“Her” is not a nominative case pronoun but rather, an object pronoun. You can say “her and me” when you need the objective case (which includes the dative case and the accusative case).

Dative case: The teacher gave her and me extra credit.

Accusative case: Mom took her and me out to dinner.

When you combine two pronouns with “and,” they need to be in the same case.

Quillbot’s free Grammar Checker can instantly find and fix errors—such as “her and I”—in your writing.
