Pride means having a feeling of being good and worthy. The adjective is proud.
The word pride can be used in a good sense as well as in a bad sense.
In a good sense it means having a feeling of self-respect. People can be satisfied with their achievements. They can be proud of something good that they have done. They can be proud of (or take pride in) their work. They might be proud of their son or daughter or husband or wife or anyone else who is close to them and who has done something good. People can be proud of their country (patriotism). The opposite would be to be ashamed of someone or something.
In a bad sense, pride can mean that someone has an exaggerated sense of feeling good. This might mean that someone has no respect for what other people do, only respect for what he or she does. Someone who is described as proud may be arrogant. The word is used in this sense in the saying: “Pride comes before a fall” (meaning that someone is so overconfident that he or she might soon have a disaster).
