HOW WORDS MOVE.
HOW MEANINGS MUTATE.

English chthonic adapts Greek khthonios with the learned chthon- spelling and English adjectival pronunciation.

Of the earth and under the earth develops into the specialized underworld sense.

Greek khthonios is formed from khthōn, earth, with adjectival morphology.

Earth becomes of the earth, including what lies in or under it.

Greek khthōn reflects the Indo-European o-grade *dh(e)ghom-.

Earth preserves the root meaning.

The o-grade *dh(e)ghom- is a vocalic formation of the earth root *dhghem-.

The earth meaning remains stable across the reconstructed formation.

The appendix identifies *dhg̑hem- as the oldest shape behind centum *dhghem-.

The earth field continues at the deepest reviewed level.

Middle English exhume continues into modern exhume with later pronunciation standardization.

Physical removal from burial remains primary while recovery from obscurity develops figuratively.

Middle English borrows Medieval Latin exhumare with minimal written reshaping.

The literal removal-from-earth sense is retained.

Medieval Latin exhumare is formed on Latin humus beside the prefix ex-.

Earth supplies the burial-ground object from which something is removed.

Latin humus reflects the suffixed o-grade formation *(dh)ghom-o-.

Earth and soil preserve the reconstructed meaning.

The suffixed o-grade *(dh)ghom-o- is built on *dhghem-, earth.

The earth meaning remains stable.

Middle English bride continues into modern bride with regular spelling and pronunciation history.

The newly married or about-to-marry woman remains the lexical center.

Middle English bride continues Old English brȳd.

Bride, wife, and spouse senses remain in the historical field.

Middle English deierie develops into modern dairy through vowel, spelling, and stress standardization.

A milk-production place expands to the products and industry associated with it.

Middle English deierie reflects Anglo-French deyerie or daerie with English orthographic adaptation.

The place of milk handling remains the center.

Anglo-French deyerie is formed on Middle English deie beside Anglo-French -erie.

The woman responsible for milk production becomes the base for the place where that work occurs.

Middle English deie continues Old English dǣge with regular reduction and spelling change.

Woman managing milk and food production continues the earlier female baker or servant role.

Old English dǣge reflects reconstructed Proto-Germanic *daigjōn-.

The occupational female baker or servant meaning continues.

Proto-Germanic *daigjōn- is derived from the dough base *daiga-.

A person associated with kneading or dough becomes a female baker and later servant.

Germanic *daiga- belongs to the form-and-build family under *dheigh-.

Dough and kneading specialize the broader act of forming.

Middle English ficcioun develops into modern fiction through French-influenced spelling and English pronunciation.

Mental invention expands into narrative, imaginative, legal, and pretense senses.

Middle English ficcioun borrows Middle French fiction with English orthographic adaptation.

Invention and feigning senses continue.

Middle French fiction continues the borrowed Latin action noun fictiō.

Shaping, feigning, and pretense narrow and reorganize in French and English.

Latin fictiō is formed from the variant stem fig- beside the action suffix -tiō.

The action of shaping or molding extends to feigning and pretense.

Latin fig- is the variant stem of fingere used before the action-noun suffix.

The shaping and making field remains intact.
