I think the word that you're asking for was DENOTATION which means ---> a specific or direct meaning of word.
Positive (one of the animals that we normally take care at home like in a piggery in our backyard wherein after sometime we can be able to sell them and have some money to support the schooling of your kids.), and also once slaughtered, we buy and cook the pig's meat into a delicious meal.
Negative: The smell of the pig or piggery kinda smelly and it causes pollution around the area because it encourages a lot of flies to flock the area where the piggery is located.
Also eating too much of pig's meat (especially the fat ones) gives you hypertension, and other illnesses.
