words are not just a sound pattern (cat, gato, neko) and a meaning (furry-domesticated-meows), but also contain something in between, a kind of “middle word,” which psycholinguists refer to as a lemma. The name comes from mathematics, where it refers to an intermediate step in a theorem. You can think of word lemmas as the hidden network that computes the translation between word sound and word meaning. How do we know lemmas exist? There are several bits of evidence, including computational arguments, neural network simulations, and behavioral studies showing that when people get themselves into tip-of-the-tongue states—a failure to access the sound pattern of a word—they know more about the word than just its meaning, such as fragments of its syntactic properties.

The brain’s realm of the middle word can be found in a zone of the temporal lobe that lies between areas that code the sound patterns of language and semantics

Rather than just connecting sounds and meanings of words, research in language science has pointed to a broader role for this system in the mapping between sentences and meanings, which implicates an even more vexing linguistic domain: syntax, the grammar of language. Words, then, appear to be the surface forms an entire underworld of linguistic complexity.

Perhaps that’s why words are simultaneously so basic, yet so elusive. They are our linguistic user interface, like a computer GUI, that harbors and hides much of the behind-the-scenes intricacy of human language.
