Wikipedia has an article about

Truth is the correspondence between and one's beliefs about reality and reality.

Alfred Tarski defined truth in terms of an infinite family of sentences such as:

"The sentence 'snow is white' is true if and only if snow is white."

To understand whether a belief is true, we need (only) to understand what possible states of the world would make it true or false, and then ask directly about the world.

'Truth' is a very simple concept, understood perfectly well by three-year-olds, but often made unnecessarily complicated by adults.
