When we say tongue
When we talk of tongue, we talk of mother tongue (langue maternelle in French and Muttersprache in German, to name two tongues other than English).
Although fathers also come equipped with tongues, I’ve never heard of a father tongue. Have you?
Mother tongue is okay but mother langue doesn’t exist. That’s because langue is French for tongue and 475 years ago, when modern English was invented, langue didn’t get translated from French to English.
Why is that? Your guess is as good as mine.
Had langue been translated from French to English, we would now say tonguage when we say language. Not only that, but it would also come with the added benefit of knowing what we’re talking about.
But given l’m all alone, I’m not even thinking of turning back the clock all by myself for that would achieve nothing but make me a 2025 version of Don Quixote.
All I’m trying to make sure is knowing what we’re talking about.
Language
Though language ought to be tonguage (see above), it’s now understood to be a means of communication that may, or may not, include words.
Wordless means of communication are also known as non-verbal or void of words. Wordless communication include body language (facial expression, gesture, eye contact, posture, touch, appearance), sign language, flags, morse, light, color, and sound, to name a few.
Communication void of words has been practiced for billions of years between the sun and everything else in the universe — the planets, stars, and moons, to name a few. Also between the fire, air, earth, and the water, between the plants and the animals, between the mushrooms and the trees, and the list goes on.
Only between the word-users is wordful communication practiced, but only since the invention of words 13,750 years ago when the age was stone, the Sahara green, and Northern Europe under 1-mile-thick ice.
Takeaway
Word and language are different for a reason.
Anyone claiming word and language are the same doesn’t know the first thing about either.
On that I give you my word.
