The philosophical study or science of truth, including its nature, conditions, criteria, and relationship to reality and knowledge.
Aletheia (Greek, truth) + -ology (study of, from logos meaning 'reason' or 'word'). A systematic discipline examining what truth is and how it functions.
Alethiology is truth science—a framework for asking whether truth is absolute or relative, single or multiple, knowable or mysterious—and it's remarkable that philosophers haven't made this term more popular given how central truth is to human knowledge.
