Read this sentence. What part of speech are the highlighted words?

grace and agility of a gymnast with the flexibility of a contortionist and the dexterity of a juggler.

blue-ish green stones. When we describe something that does not exactly match an adjective, we use -ish This is commonly used when a colour is between two colours. If someone asks, "What colour is turquoise", you could answer "It is greenish blue" Note: the final colour takes the usual form.
