Can language models learn meaning from text patterns alone?

Explores whether training on form alone—predicting the next word from prior words—could ever give language models access to communicative intent and genuine semantic understanding.

What kind of thing is an LLM really? How do you navigate synthesis across fragmented research topics?

Bender & Koller (2020) make a specific structural argument, not just an intuitive one. Meaning is defined as the relation M ⊆ E × I — pairs of natural language expressions and the communicative intents they can be used to evoke. Understanding language means retrieving i given e. But communicative intents are about something outside of language. Form alone — marks on a page, pixels, bytes — is insufficient.

The reasoning: without access to a mechanism for hypothesizing and testing underlying communicative intents, reconstructing them from form alone is impossible. Language modeling predicts the next token given prior tokens — purely a form-to-form operation. The training signal provides no information about what intents the forms were used to evoke.

Human language acquisition illustrates the point by contrast. What is critical for meaning acquisition is not just interaction but joint attention — situations where child and caregiver both attend to the same thing and are both aware of this fact. Learning meaning requires the ability to be aware of what another person is attending to and guess what they are intending to communicate. Intersubjectivity is not incidental to language learning; it is its mechanism.

The Harnad formulation (symbol grounding problem): a non-speaker of Chinese cannot learn the meanings of Chinese words from Chinese dictionary definitions alone. You need something outside the symbol system to anchor the symbols. Form-to-form prediction cannot provide this anchor.

Mutual understanding is structurally unavailable — even in conversational media. The form-only training constraint has a downstream consequence that applies even when AI operates in conversational channels: seeking mutual understanding with the user is structurally unavailable to an LLM because mutual understanding requires the intersubjectivity that form-training cannot provide. The communication is one-way even when it occurs on a medium designed for mediated social interaction. This reframes AI social-media posts as a specific genre: indirect discourse that is a form of writing even when it appears in an interactive environment. The user reads the post, the medium formally supports reply, but the AI is not available for the second turn that would close a loop of mutual understanding — and was never going to be. The channel looks communicative; the content is monological writing that happens to be deposited in a conversational shape.

This is distinct from the claim that LLMs "have no understanding." It is the more precise claim that the training mechanism — string prediction — is in principle incapable of providing the signal that meaning acquisition requires, regardless of scale.

This note is a source for these research framings, grouped by the broader line of inquiry each explores. Scan the bold lines of inquiry; follow any specific question forward.

Does conversational format create illusions of genuine AI communication? Is embodied interaction necessary for language meaning and genuine agency? How do training priors constrain what context information can override? How do language models establish social grounding in human dialogue? Do language models understand semantics or rely on pattern matching? What articulatory information do speech signals carry that text cannot? Do language models learn genuine linguistic structure or just surface patterns? Do language models perform faithful symbolic reasoning independent of semantic grounding? What structural advantages do diffusion language models offer over autoregressive methods? How do formal dialogue structures reveal conversation coherence mechanisms? Can next-token prediction alone produce genuine language understanding? Should GUI agents use structured representations instead of raw pixels? How do language models inherit human biases from training data? Why do benchmark improvements fail to reflect actual reasoning quality? How should conversational agents balance goal-driven initiative with user control? Do language models develop causal world models or rely on statistical patterns? Why do language models struggle with implicit discourse relations? Do language model representations contain causally steerable task-specific features? Why can't humans reliably detect AI-generated text despite measurable linguistic signatures? Which computational strategies best support reasoning in language models? What factors beyond surface content determine how readers extract meaning differently?
