Would one use a semicolon in lists where each item in the list has multiple words, for example: To be part of a team; to have a leader; to eat pie. Or is a comma used?
Yes, a semicolon would be used instead of a comma.
I'm currently going through a lesson in English on the topic of semicolons, and I was told that they would only be used when there are items to separate in a list when commas would be confusing. Here are some examples:
On a trip, we drove through Tampa, Florida; Wichita, Kansas; and Fresno; California.
The group was composed of three young people: Mary, who was 32 years old; Javier, who was 28 years old; and Mind, who was 17 years old.
The answers to the test are: 1, A; 2, D; 3, F; and 4, B.
Use semicolons between items on a list only if there are "internal" commas within the items themselves.
You use semicolons between items on a list when there are "internal" commas within the items.
The use of semicolons in a list is not related to the number of words in the items, or the length of the items.
For example, this list needs just commas because the items don't have any commas of their own:
At the store I bought bread, milk, chicken, eggs, coffee, and cheese.
Here is a list with long items using many words, but since there are no commas within the items, they are separated with commas, not semicolons:
Whole Duty of Children
~ from a poem by Robert Louis Stevenson
A child should always say what’s true,
And speak when he is spoken to,
And behave mannerly at table;
At least as far as he is able.
But this list -- with commas within the items -- needs to have semicolons between the items:
I sent invitations to Ted, my brother; Susanna, my older sister; Natalie, my younger sister; and Joanne, my only cousin.
Here's a .edu site that explains this rule:
To link lists where the items contain commas to avoid confusion between list items
There are basically two ways to write: with a pen or pencil, which is inexpensive and easily accessible; or by computer and printer, which is more expensive but quick and neat.
