Question

Чем отличается дефис от тире? Заранее спасибо

Answer 1

Дефисы могут быть просто между сложными словами и тд. 
А тире может стоять как между подлежащим и сказуемым, так и может отделять части сложносочиненного предложения друг от друга

Difference between a hyphen and a dash

A hyphen and a dash are two different punctuation marks that serve different purposes in writing. Here's a breakdown of the key differences between them:

Hyphen (-): - A hyphen is the shortest of the three punctuation marks and is used to join words or parts of words together. - It is commonly used in compound words, such as "self-confidence" or "well-known." - Hyphens are also used to divide words at the end of a line when word wrapping in typesetting. - Example: "The two-year-old child is playing in the park."

En Dash (–): - An en dash is slightly longer than a hyphen and is used to indicate a range or connection between two things. - It is typically used to represent a span of numbers, dates, or times. - Example: "The event will take place from 9:00 a.m.–5:00 p.m." or "The years 2010–2020 were significant for technological advancements."

Em Dash (—): - An em dash is the longest of the three punctuation marks and is used to indicate a break or interruption in a sentence. - It can be used to set off a parenthetical phrase or to emphasize a point. - Example: "I have three favorite colors—blue, green, and purple."

It's important to note that the usage of hyphens, en dashes, and em dashes can vary slightly depending on the style guide or language conventions. Always refer to the specific guidelines or preferences of the publication or organization you are writing for.
