The adjective 'wordy' is a straightforward native English formation. Its core, 'word', descends from the Proto-Germanic wurda-, which itself derives from the Proto-Indo-European root werh₁- meaning "to speak" or "to say". The suffix '-y', of Old English origin, is a prolific adjectival ending used to indicate a quality or abundance. Thus, the literal construction "full of words" directly and logically evolved into its modern abstract meaning, describing speech or writing that is excessively verbose or uses more words than necessary.
