Phrasal Adjective Example, List, and Guide
Hello, and thank you for your question.
First of all: What are phrasal adjectives? Adjectives describe or modify the noun. A phrasal adjective is two or more words that form a unit in order to describe the noun. In the examples that you mentioned above, 'well-behaved' and 'broken-down' are the phrasal adjectives. Here is how you can use them in sentences.
'I saw a very well-behaved child on the train yesterday'
'There was a broken-down car outside our house this morning'
I hope that the explanation and examples help you.
