Synonymy ( هم معنایی ) : This is when two or more words have very similar or identical meanings. They can often be substituted for each other in a sentence without significantly changing the meaning.
Examples:
big / large
happy / joyful
begin / start
smart / intelligent
Antonymy ( تضاد ) : This is when words have opposite meanings. There are different types of antonyms:
Gradable Antonyms: These exist on a spectrum ( e. g. , hot and cold; tall and short ) . There are degrees between them.
“The water is hot. ” vs. “The water is cold. ”
Complementary Antonyms: These are usually an either/or situation ( e. g. , alive and dead; on and off ) . If one is true, the other must be false.
“The light is on. ” vs. “The light is off. ”
Relational Antonyms: These describe a relationship from opposite viewpoints ( e. g. , buy and sell; parent and child; teacher and student ) .
“John sells books to Mary. ” vs. “Mary buys books from John. ”
Hyponymy ( شمول معنایی / رابطه زیرمجموعگی ) : This is a hierarchical relationship where one word ( the hyponym ) is a type or kind of another word ( the hypernym or superordinate ) .
Example:
Animal is the hypernym.
Dog, cat, bird are hyponyms of animal.
We can say: “A dog is a type of animal. ”
More Examples:
Hypernym: color — Hyponyms: red, blue, green
Hypernym: vehicle — Hyponyms: car, bus, motorcycle
Hypernym: chair — Hyponyms: stool, armchair, recliner
