Speaking words clearly and distinctly, or formally declaring or announcing something officially.
From Latin 'pronuntiare': 'pro-' (forward/forth) + 'nuntiare' (to announce/report). Originally meant to announce formally, then extended to include how words are spoken.
Regional accents developed partly because people in isolated communities pronounced words differently—over generations, these variations became so ingrained that linguists can pinpoint where someone grew up by their vowel sounds alone.
