One word substitution and idioms

One word substitution:
The use of a single word instead of a group of words to describe something or someone is referred to as one word substitution. For example, the term "omnipotent" refers to a person who has unlimited power. As a result, instead of saying, "God has unlimited power," one can say, "God is omnipotent."

Some important one word substitution are given below:
• A person fond of company- Gregarious
• Something that cannot be avoided- Inevitable
• A remedy for all disease- Panacea
• Safe to drink- Potable
• Violation of what is regarded as sacred- Sacrilege
• A perfect society free from poverty and sufferings- Utopia
• Government by the wealthy- Plutocracy
• A building where weapons and military equipment are stored- Arsenal
• A large burial ground, especially one not in a churchyard- Cemetery
• A large building in which aircraft are kept- Hangar
• A small shelter for a dog- Kennel
