When expressing a tendency to prove or display something, "tend to show" can be replaced with various synonyms to enhance the sentence's meaning. "Suggest," "indicate," or "imply" all imply some degree of probability or a hint of truth that points towards a conclusion. "Demonstrate" is more direct and implies certainty, while "reveal" implies the uncovering of something previously hidden. "Manifest," "betray," and "unveil" all express the idea of making something known or visible, while "evidence" is a noun that can be substituted for "tend to show." By using different equivalents, writers can vary their language and express different shades of meaning.
