Explain with examples, the basic units of grammar.

Here are the basic units of grammar with examples:

• Phonemes: These are the smallest units of sound in a language that can distinguish meaning. They don't have meaning on their own.
  • Example: In English, the sounds /p/ and /b/ are phonemes because they change the meaning of words like "pat" and "bat."
• Morphemes: These are the smallest units of meaning in a language. They can be free (stand alone as words) or bound (must be attached to other morphemes).
  • Example: In the word "unhappiness," "un-" (bound, meaning not), "happy" (free, a word), and "-ness" (bound, meaning state of being) are morphemes.
• Words: These are units of meaning that can stand alone and are typically made up of one or more morphemes.
  • Example: "Cat," "run," "beautifully," "quickly."
• Sentences: These are complete units of thought, usually containing a subject and a predicate, that express a statement, question, command, or exclamation.
  • Example: "The dog barked loudly."
