Origin
From Greek lambanein meaning 'to seize,' lemma — literally 'that which is taken for granted' — became simultaneously a logical premise, a mathematical stepping stone, and the dictionary headword that captures all variant forms of a word under a single canonical identity.

The Full Story
Ancient Greek5th century BCEwell-attested
The word 'lemma' derives from Ancient Greek λῆμμα (lēmma), meaning 'something taken, something received, a thing taken for granted, a premise or assumption.' It is a nominal derivative of the verb λαμβάνειν (lambanein), 'to take, to seize, to grasp,' formed with the suffix -ma indicating the result of an action — hence literally 'that which is taken or assumed.' In Greek philosophical and logical discourse, particularly

The word 'lemma' shares its Greek root lambanein ('to seize') with epilepsy, narcolepsy, catalepsy, syllable, dilemma, and prolepsis — meaning your dictionary's headword system, a neurological seizure disorder, a unit of pronunciation, and a logical trap all descend from the same ancient verb for grabbing something with your hands. When a lexicographer lemmatizes a text, they are, at the etymological level, performing a mass seizure of words.
entered Latin as lemma with the same logical and mathematical senses. By the early modern period, lexicographers adopted 'lemma' to mean the headword or citation form of a word in a dictionary — the form 'taken' as representative of all its inflected variants. This lexicographic sense reflects the original Greek notion of something selected or assumed as canonical. The deeper ancestry traces to the Proto-Indo-European root *sleh₂gʷ- (also reconstructed as *(s)lagʷ-), meaning 'to seize, to take, to grasp.' This root, with its s-mobile prefix that could appear or disappear, gave rise to Greek lambanein through regular phonological development. The same PIE root produced several other Greek derivatives sharing the core semantics of taking or seizing: 'syllable' (from Greek syllabē, 'a taking together' of sounds), 'dilemma' (from di- + lēmma, 'a double assumption,' a choice between two premises), 'prolepsis' (from prolēpsis, 'a taking beforehand,' anticipation), 'epilepsy' (from epilēpsis, 'a seizing upon,' referring to seizures), and 'catalepsy' (from katalēpsis, 'a seizing down,' a trance-like state of rigidity). All preserve the ancient notion of grasping or taking. Key roots: *sleh₂gʷ- (Proto-Indo-European: "to seize, to take, to grasp"), λαμβάνειν (lambanein) (Ancient Greek: "to take, to seize, to receive"), λῆμμα (lēmma) (Ancient Greek: "something taken, a premise, an assumption").
