Inner Form — a Language's "Shape" Is Neither Its Sounds nor Its Rules

The overview said “the form of a language is the constant way it turns thought into sound.” An abstract phrase. What does it point to concretely? Here Humboldt’s “form (Form)” is unpicked from the German.

1. Material (Stoff) and form (Form)

Every language has a material (Stoff) common to all: the voice-making body, and the world of what can be thought. But how that material is organised differs by language, and this organising is the form (Form). Humboldt is emphatic that form is not an assemblage of small rules: no particular may enter the concept of the form of a language “as an isolated fact, but only in so far as a method of language-formation (eine Methode der Sprachbildung) can be discovered in it” (German quotations throughout; Japanese and English are L/LAB working translations).

So “English has third-person-singular -s” is not, by itself, form. Only when you can read off from it how English chooses to lock subject and predicate together does it become a matter of form.

2. Outer form and inner form

Humboldt’s “form” has two faces. Outer form (Lautform) — the sound system, the shape of words, word order. And, working beneath it, an inner form — how concepts are made, which grammatical categories (tense, number, case, voice…) are set up, how word is related to word, where the continuum of thought is cut into segments. When Humboldt says “this differs by language,” he chiefly means this inner face. Hyman Steinthal later tidied it into one term: the “inner form of language (innere Sprachform).”

3. A language presents not “objects” but “ways of grasping objects”

Humboldt’s famous example.

When in Sanskrit the elephant is called now “the twice-drinking,” now “the two-tusked,” now “the one furnished with a hand,” Humboldt notes, “so many different concepts are thereby designated, even though the same object is always meant.” His reason:

Denn die Sprache stellt niemals die Gegenstände, sondern immer die durch den Geist in der Spracherzeugung selbstthätig von ihnen gebildeten Begriffe dar.

For language never presents the objects, but always the concepts formed from them, actively, by the mind in the generation of language.

A word is not a label stuck on an object. A word fixes how the mind grasped the object. “The twice-drinker” and “the two-tusked one” may look like synonyms in a dictionary; at the level of inner form they are different concepts.

4. Hence, in translation, the “form” slips

Same object, different grasp — this becomes conspicuous across languages. English home and house; the range Japanese ao covers (traffic lights, young leaves, the sea); how kinship is cut (English brother vs Japanese “elder brother / younger brother”). The referents overlap, but because the inner form differs, they do not carry the same value. Translation is hard not for want of vocabulary but because the way concepts are cut — the form — does not line up. Humboldt carries this into the theme of the next piece, worldview.

5. To Saussure, Sapir, Weisgerber

• Saussure — “in a language there are only differences.” The value of a sign is fixed by its place in the system. French mouton and English sheep overlap in meaning but not in value. This is Humboldt’s “inner form differs by language,” recast in terms of a system.
• Sapir — form (method) and function (concept) are independent. Parts of speech are the language’s cut, not nature’s. “All languages are formal languages.”
• Leo Weisgerber — in twentieth-century German linguistics, developed Humboldt’s inner form into a “linguistic intermediate world (sprachliche Zwischenwelt)”: we face the world not directly but through the intermediate world our mother tongue has assembled.

In sum

Humboldt’s claim	restated
Material (voice, the thinkable) is common; form is language-specific	not what you have, but how you organise it, divides languages
Form is not an isolated fact but a consistent “method”	not “there is an -s” but “how subject and predicate are locked together”
Inner form = how concepts, categories and relations are made	“inner form of language” is Steinthal’s coinage
A word presents not an object but “a way of grasping” it (a concept)	the three Sanskrit words for “elephant”
→ Saussure’s value, Sapir’s form/function, Weisgerber’s intermediate world	“where you cut the continuum” is form

Why it is still read

• “Form is the essence of language” — this intuition passed on as a shared premise of Saussure’s structural linguistics and Sapir’s descriptive linguistics.
• Semantics and typology — “each language cuts concepts differently” is the starting point of contrastive work on colour terms, kinship, spatial language (modern semantic typology).
• The basis of linguistic relativity — how differences of inner form bear on thought is taken up head-on in the next piece, worldview.
