Contingency Table Confusion NLP

Hello for the contingency table: [true positive, false negative, false positive, true negative]. I am having a hard time remembering the difference between these terms because all the terms are composed of words which have a high similarity with each other but they are used in such opposing contexts. The only ones that make sense is true positive and false negative but the other ones I always get mixed up and is wondering is there some quick mnemonic I can use?
