Morphology

tautology = tauto + logy

Although the word is historically built from Greek elements meaning 'same' and 'saying', the logical sense 'a statement true in all interpretations' is a specialized technical meaning that is not predictable for most learners from the parts.

Etymology

Tautology comes from Greek parts tauto- meaning 'the same' and -logy from logos meaning 'word' or 'reason'. In logic a tautology is like a 'same-word' statement that stays true in every case, which is why it cannot be false.
