Hyphens · Grade 8
In Grade 8 you get fluent with: hyphens in describing words: a well-known writer; hyphens in numbers and fractions; hyphens that change the meaning: re-sign and resign.
A hyphen - is a short mark with no spaces that joins words or parts of words: a well-known writer, re-enter, twenty-one. Joining words with a hyphen can change what they mean.
Key facts
- Two or more words that work together to describe a noun take hyphens: a part-time job, a ten-year-old boy, an up-to-date map.
- No hyphen after a word ending in -ly or after very: a brightly coloured kite, a very tall tree.
- Numbers from twenty-one to ninety-nine have a hyphen, and so do fractions in words: forty-seven, two-thirds.
- A hyphen can change the meaning: re-sign (sign again) and resign (leave a job); a man-eating shark (a shark that eats people) and a man eating shark (a man who is eating shark).
