Hi. You did not provide the phrases this question refers to. This makes it impossible for me to answer your question efficiently. However, I will try to help you as best I can.
Context clue is a literary device that allows the reader to understand the meaning of a difficult or unknown word through the context of the sentence where it is inserted or the context of the text itself.
This context clue will be called definition clue when the phrase presents the meaning of the word in its composition. Ex: Uma Haberdashery, which is a men's clothing store, opened next to my mother's restaurant.
The context clue will be called example clue when the phrase presents examples to explain the unknown word. Ex: My mother could not stand people who behave in an obsequious way, like my sister who was full of flattery in relation to her boss.
The context clue will be called synonym clue when the unknown word is explained subjunctively within the sentence. Ex: My mom was happy when the new haberdashery opened because she needed to buy a new suit for my dad.
The context clue will be called antonym clue when the meaning of an unknown word is determined by the presentation of another word or a clause that presents the opposite of that word. Ex: But my mom was sad that she couldn't buy women's clothes in this store, as it was a haberdashery.
