Etymologists work hard studying languages. This study involves the proposal of languages that appear to have existed & can be built based on the products of these languages’ progeny. One such proposed source language is Proto-Indo-European, & one of the root words etymologists believe came from this proposed language is a word meaning speak. Though this root word was never written when this proposed language was spoken (assuming it was spoken), we write the root *wekw-. It appears to have given birth to a steaming heap of English words.
After passing through Latin:
vociferous - 1600s
vocabulary - 1500s
avocation - (we also refer to an avocation as a calling — & isn’t a calling voiced?) 1400s
After passing through Latin, Old French & Anglo-French:
vouch - 1300s
After passing through Latin & Old French:
voice - late 1200s
vowel - 1300s
vocal - late 1300s
invoke, revoke, provoke, & evoke — 1400-1600s
convocation - 1300s
advocate - 1300s
equivocate - late 1300s
And after passing through Greek & Latin:
epic - 1500s
All that from the idea of speaking up.
Voting day is soon upon us. Speak up.
