Keith Kelly looks at examples of language used in forming complex noun and adjective phrases from the area of geography, which contain a mixture of nouns, verbs, adjectives, adverbs and prepositions.

Compound adjective phrases

It is rare to find more than two or three adjectives placed in sequence together in everyday speech. There is a standard word order for multiple adjectives: opinion, size, age, shape, colour, origin, material.

These phrases occur more frequently in geography texts and they are frequently similar in category and so less easy to order according to the rule above (e.g. Glaciated valleys are deep, straight, steep-sided, U-shaped valleys with flat floors). As a general rule, the adjective which is closest to the related noun in meaning comes first. It is usually describing a permanent characteristic, while other more variable characteristics come last.

Compound noun phrases

Nouns are modified using other words such as adjectives, other nouns or present (-ing) or past (-ed) participles. Modifying nouns function in a similar way to adjectives, and they are created with new ideas, as new needs arise for new terms.

Phrases made by linking two (or more) nouns to express multiple relevant characteristics in one phrase. Note that these nouns can be standalone items, connected with a hyphen or compounded into one word.

boulder clay hills: Drumlins are oval-shaped boulder clay hills.
