Hyphenated Compound Adjectives
Compound adjectives, such as 'hard-working' and 'well-respected', are formed by combining an adjective or adverb with a present participle or past participle, respectively. These compound adjectives, always written with a hyphen, help provide more precise descriptions in writing.
Hyphens in Numbers and Time Expressions
Hyphens are used in numbers from 21 to 99 before a noun, such as '18-year-old students'. The same rule applies to time expressions, like 'last-minute decision'. However, hyphens are not necessary when indicating numbers after the noun, for example, 'the students are 18 years old'. Additionally, compound adjectives with an adverb ending in '-ly', such as 'carefully written', do not require hyphens.
