A lemma is a term or phrase that’s being defined or explained. Huh? Here it is in action – when you look up a word in a dictionary or, more likely these days, type a word into a dictionary search bar, the word you’re typing is called a lemma.
Lemma has its origins in ancient Greek. It’s derived from the Greek word ‘λῆμμα’ which means ‘something taken’, ‘an assumption’ or ‘a proposition’. It’s the noun (person, place or thing) form of the verb (doing word) ‘λαμβάνω’, or ‘lambanō’, which means ‘to take’.
The plural of lemma is either ‘lemmas’ or, if you’re feeling a bit arcane, ‘lemmata’. And it’s also where we get the word ‘dilemma’ from – which is ‘lemma’ in the sense of a proposition, with ‘di’ meaning ‘two’ at the start – two propositions.
All of this emma-based etymology caused me to ask ChatGPT what my name means. He told me it comes from the Germanic word ‘ermen’ or ‘irmin’, which means ‘whole’ or ‘universal’. He went on to say that Emma is ‘a classic name that carries a sense of timelessness and elegance’. Fingers crossed he wasn’t just buttering me up before he steals my job and brings about Judgement Day.
If you’re not a fan of ‘lemma’, another word for a term being defined is a ‘definiendum’. It’s fun to say, and will deffo make you sound like a smarty pants. You’re welcome.
