Synonyms are words which have almost the same meaning for the given context.
Since some words have multiple meanings, one must specify the meaning associated with a synonym.
Dictionary, Thesaurus, Lexicon and Vocabulary are synonyms. Their usage depends on the context.
- In general, Lexicon is a body of knowledge (or dictionary) of Latin and Greek.
- At one time, Lexicon is a card game where players create words and score points. It was superseded by Scrabble.
Antonyms are words which have almost the opposite meaning for the given context.
Since some words have multiple meanings, one must be careful of the meaning associated with an antonym.
For example, Love and Hate are antonyms.
In Pali, the antonyms of Lobha (Greed), Dosa (Anger or Hatred) and Moha (Ignorance of Delusion) are Alobha (Non-greed), Adosa (Non-hatred) and Amoha (Non-ignorance or Wisdom).
