So as to help others who may be having the same problem, first allow me to explain what connotation means.
A connotation is a feeling or idea that a word raises both a figurative and literal meaning for a person.
In your tag bar, you mentioned the words "house=home." This would be a connotation given that when some people hear the word house they automatically think of the word home as well. A house does not only illustrate a building structure which people live in. It also illustrates the place where families live and call their home--the place where they belong.
Therefore, three other examples of connotations are:
1. Chicken- The literal is the animal, the figurative is a cowardly person.
2. Shrimp- The literal is the sea creature, the figurative is a person who is small.
3. Pig- The literal is the farm animal, the figurative is someone who would eat a lot or does not bathe.
