Examples of lexical morpheme
Now, the best way to know what a lexical morpheme is is to see it in examples. Next, we can observe the minimum unit with lexical meaning , that is, a part that does not vary, but which is the lexeme, which we see in capital letters:

• 
  Sport
  
• 
  Sports
  
• 
  Sports player
  

As we observe below, the lexemes join the morphemes, expressing grammatical meaning:

• 
  Modern
  
• 
  MODERN
  
• 
  MODERN
  

Other types of morphemes
As we have already commented on many occasions, our language is very rich, due to which there is a great variety of grammar and spelling rules, as well as different types. In this case, we can observe different classes of morphemes:

• 
  Free morpheme , which is the one formed by the word itself, without additions: flower, clock, sea.
  
• 
  Linked morpheme , which appears next to another morpheme: flourish, truck.
  

They are also known as lexemes, so you might see them by these two names:

• 
  Independent lexem , which is not attached to a morpheme: for, and, two.
  
• 
  Dependent lexem , which joins other morphemes: pat-o, cam-a.
  

Furthermore, it should be added that the list of lexical morphemes can be expanded at any time when new meanings or words are incorporated into the language.
Morpheme properties
Finally, we are going to know some properties that are inherent to all morphemes, and that help them to be identified more easily:

• 
  Every word is made up of morphemes.
  
• 
  A morpheme can never be decomposed into a minor element that has meaning on its own.
  
• 
  A morpheme can be part of several words, but it will not always repeat its function and meaning.
  
• 
  A morpheme can have various phonetic forms, a phenomenon known as allomorphs .
