List of One Word Subsitution in English

One Word Substitution

Overview:

A one-word substitution is when a single word is used instead of a long phrase or sentence. It makes writing and speaking clearer and more concise.

For example:

A person who writes a book → Author
A place where birds are kept → Aviary

One-word substitutions are beneficial for exams like:

IELTS, TOEFL, and PTE (for English proficiency)
GRE and GMAT (for vocabulary-based sections)
SSC, Bank, and UPSC (for competitive exams in India)
SAT and ACT (for college entrance tests)

Learning these words not only helps in exams but also improves communication skills.
