Words. Where they came from. How they shifted. Who benefits from the shift.

A living glossary of words whose meanings have shifted. Each entry: word, origin, original meaning, when it changed, who benefits from the change. Where a memo on the site unpacks a word at length, the entry links to it.

Entries listed in the order they were added — newest first.

M /ɛm/ · the letter, the sound, the picture
A letter · Egyptian hieroglyph · c. 3000 BCE · via Proto-Sinaitic and Phoenician
Original meaning Water. The letter M descends from the Egyptian hieroglyph for water — a zigzag of three or four ripples (Gardiner sign N35: 𝃠). Semitic miners working at Serabit el-Khadim and Wadi el-Hol around 1800 BCE adapted the sign for the first letter of their own word for water, mayim. The letter’s name in Phoenician, Hebrew, Aramaic, and Arabic is mem / mīm — the West Semitic word for water itself.
Shifted to The Phoenicians passed the angular wave-shape 𐤌 to the Greeks, who straightened it into Μ, then to the Romans as M. The Greek and Latin letters lost the meaning — they kept only the sound. But the original referent never quite left the words it opens. Every European language for sea begins with M (Latin mare, French mer, Spanish mar, German Meer, Welsh môr, Irish muir, Russian more). Hebrew mayim, Arabic mā’, and Aramaic mayya all still mean water and still open with the wet letter that is water.
When Egyptian water hieroglyph c. 3000 BCE. Proto-Sinaitic adaptation c. 1800 BCE. Phoenician mem c. 1050 BCE. Greek Μ c. 800 BCE. Roman M c. 700 BCE. The shape on the page in this sentence is, structurally, still the Egyptian ripples — five thousand years of continuous descent.
Who benefits No one engineered the M’s meaning; the loss of its meaning in Greek and Latin was incidental, not intentional. But the consequence is significant: a culture that no longer remembers its letter for water is a culture less in touch with water’s primacy — the first substance, the womb, the sea, the threshold every life is delivered through. The water-letter still does its work in every word starting with M. The forgetting is the cost.

M is also biomechanically the closed-mouth sound — lips sealed, voice vibrating internally. It is the sound the infant makes at the breast (mmm, mama, mère, māmā) and the sound of pleasure in tasting. It is the seed-syllable that closes Om in Hindu and Buddhist mantra. The letter for water is also the letter for the first sound the human mouth makes when something is contained, held, internal, wet. Not coincidence: design.

From Moriah to the Morel: Following the MOR Root Through Human Language

The MOR memo follows the m-r phoneme across five thousand years. A dedicated memo on the letter M itself — the hieroglyph, the closed-mouth sound, the water-symbol — is the natural sequel.

MOR /mɒːr/, /mɛr/, /mʊr/, /mær/
A phoneme — not a word · Attested c. 2500 BCE · Sumerian, Akkadian, Egyptian onwards
Original meaning The phonetic sequence m-r appears across the oldest writing traditions on Earth in association with death, the sea, bitterness, sacred substances, the cosmic frontier, and the standards that hold civilisation against the abyss. Akkadian murru = myrrh; marru = bitter. Sumerian MAR.TU = the western frontier. Egyptian mer = pyramid. Hebrew mor = myrrh, mar = bitter, Moriah = the temple mount. Sanskrit mṛtyu = death.
Shifted to Carried into modern English across eight word-families: death (mortal, murder, morgue, mortgage), sea (marine, mermaid, mer), frontier (moor, march, margin), standard (moral, morality, mores), folly (moron), memory (memorial, mourn), increase (more, most), and mother (Mary, Maria, Mater). One phoneme, every fundamental mystery.
When Documented continuously from Akkadian cuneiform c. 2500 BCE to the present. The most striking pattern is structural rather than chronological: three unrelated civilisations — Hebrew, Egyptian, Hindu — name their most sacred mountain with the same phoneme (Moriah, Mer, Meru).
Who benefits No one engineered this. The cluster is too old and too widely distributed to be a manufactured meaning. What benefits is the inverse question: who benefits when the pattern is forgotten? When the standards we live by (mores) lose their connection to the abyss they hold back (mor as death, sea, threshold), the boundary becomes invisible — and invisible boundaries are easier to dissolve.

The deepest signature in human language, hidden in plain sight in every sentence we speak. Used dozens of times a day in the simplest of words — more — without anyone noticing it carries the weight of five thousand years.

The Benben: The Risen Mound, the Phoenix, and the Sound of “Ben”

Egypt’s primeval mound of creation, the capstone of every pyramid, and the phoenix that rose from it all carry one root — wbn, “to rise, to shine.” The Semitic word for “son,” ben, only sounds like it. The facts of both, the look-alikes the sound throws off across unrelated languages — Chinese, Sanskrit, even Tibetan Bön — and one open question, does anything older connect them, left for the reader to weigh.
