* Perfect Synonyms: These are words that have exactly the same meaning in all contexts. They are rare, and often one word might be more common or preferred in certain situations.
* Near Synonyms: These words have similar meanings but differ in nuances, connotations, or shades of meaning. For example, "happy" and "joyful" are near synonyms, but "joyful" implies a more intense and exuberant happiness.
* Cognitive Synonyms: These are words that have the same basic meaning but are used in different contexts. For example, "begin" and "commence" have the same meaning but "commence" is more formal.
* Stylistic Synonyms: These words have the same meaning but differ in their style or register. For example, "start" is informal, while "initiate" is formal.
Based on Formality:
* Formal Synonyms: These words are more formal and are often used in academic writing or professional settings. For example, "terminate" is a formal synonym for "end."
* Informal Synonyms: These words are more casual and are often used in everyday conversation. For example, "cool" is an informal synonym for "awesome."
Based on Relationship to the Original Word:
* Strict Synonyms: These words have the same meaning and can be used interchangeably in most contexts. They are less common than near synonyms.
* Loose Synonyms: These words have a similar meaning but may not be interchangeable in all contexts. For example, "happy" and "content" are loose synonyms, as "content" can imply a more passive state of satisfaction.

* Homographs: Words that are spelled the same but have different meanings and sometimes different pronunciations (e.g., "bow" as in a bow tie and "bow" as in to bow your head).
