The Science of Language, a free language course on Tomo

The Science of Language

Examine the invisible operating system that powers human speech. Learn how sounds and sentences obey rigorous mental rules, how historical sound shifts reshape vocabularies, and why a single ancestral tongue splinters into thousands.

Like Duolingo, but for The Science of Language. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Decoding the Universal Mechanics and How Tongues Mutate and Multiply. It assumes you already know the basics.

What you'll learn

Key ideas in The Science of Language

  • Voicing specifies whether the vocal folds vibrate during sound production.
  • Place identifies the physical point of contact in the vocal tract.
  • Manner describes how the airstream is shaped or constricted during speech.
  • Voiceless stops aspirate with a puff of air at the start of stressed syllables.
  • After an initial /s/, voiceless stops become unaspirated without a puff of air.
  • Between vowels or before syllabic consonants, /t/ shifts to a tap or glottal stop.
  • Phonotactic constraints define permissible sound sequences in a given language.
  • Languages insert vowels (epenthesis) to break up illegal consonant clusters.
  • Borrowing forces foreign words to systematically reshape into native syllable molds.
  • Place assimilation shifts a sound's contact point toward an adjacent consonant.
  • Anticipatory assimilation prepares articulators early to conserve muscular effort.
  • The alveolar nasal /n/ shifts to the bilabial nasal [m] before bilabial stops [p] and [b].
  • Words group into hierarchical branches called constituents rather than simple bead-like strings
  • Prepositional phrase attachment to a verb modifies the action, while attaching to a noun modifies the person
  • Structural ambiguity occurs when identical word strings can form two distinct valid syntactic trees
  • Substitution replaces an entire suspected constituent with an equivalent pro-form like a pronoun
