3d: Adjective Phrases and Clauses

Reduced relative clauses

When the relative pronoun is the subject of the relative clause, the relative clause could be ‘reduced’. Reduced relative clauses can make the writing more concise and add variety to sentences. A relative clause can be reduced to:

i) an adjective phrase

Hand, foot, and mouth disease is a contagious disease which is prevalent among children under 5.
Can be reduced to -> Hand, foot, and mouth disease is a contagious disease prevalent among children under 5.

Notes:
A related kind of structure that adds additional information is called appositive phrase, which consists of two nouns/noun phrases that refer to the same person/thing. For example,

Ieoh Ming PEI, who was a Chinese-American architect, designed the Louvre Pyramid in Paris and the Bank of China Tower in Hong Kong.

Can be reduced to -> Ieoh Ming PEI, a Chinese-American architect, designed the Louvre Pyramid in Paris and the Bank of China Tower in Hong Kong.

ii) a present participle phrase

Shops that offer delivery service are popular during the pandemic.
Can be reduced to -> Shops offering delivery service are popular during the pandemic.

Notes:
If the relative clause is in the active voice, it can be reduced to a present participle phrase (verb + -ing).

iii) a past participle phrase

Cheung Sha Beach, which is located on Lantau Island, is the longest beach in the Hong Kong area.
Can be reduced to -> Cheung Sha Beach, located on Lantau Island, is the longest beach in the Hong Kong area.

Notes:
If the relative clause is in the passive voice, it can be reduced to a past participle phrase.
