Conjunctions are words used to connect phrases and clauses. Between 25 and 40 months, children begin to use the conjunctions and and because (Owens, 2001) to join phrases and clauses. And is the most frequently used conjunctive form for children in the three- to five-year age range.
The hyphens are unnecessary in sentence 1 because the phrase five years of age is not being used as a single adjective. In sentence 2, however, the phrase five-year-old is being used as a single descriptor for the noun boy.Not one of the words in that phrase would work alone; that is, he is not a five boy, a year boy, or an old boy. We have to pull all those words together to form a single adjective.The hyphen in sentence 3 is correct because we always use a hyphen in compound numbers between twenty-one and ninety-nine.he descriptions too-tall-to-tango and bramble-covered are also correctly hyphenated in sentence 6 because they precede the nouns they modify. Notice that we did not include the word tough in the hyphenated phrase too-tall-to-tango because it is a separate adjective.
