Lambda or Lamda – Quick Answer
Lambda is the correct spelling.

Incorrect: The lamda symbol is used in math.
The Origin of Lambda or Lamda
The word lambda comes from Greek. It is the 11th letter of the Greek alphabet. In contrast, lamda has no origin at all. It exists only because people mishear the word.
In Greek, the word is written as Λάμδα. However, the sound feels like “lam-da.” Therefore, many people drop the second b when spelling it. As a result, the wrong version spreads fast.
Moreover, English borrowed many Greek words. However, English kept the original spelling. Therefore, lambda stayed correct in all fields. Meanwhile, lamda never became valid. Overall, history supports only one form. That form is lambda.

British English vs American English Spelling
Some people think this is a US vs UK issue. However, that idea is false. Both American and British English use lambda only.
| Aspect | British English | American English |

In contrast to words like “color” and “colour,” this word does not change. Therefore, location does not matter. Additionally, academic writing follows the same rule worldwide.
So, whether you write for the US or the UK, use lambda.
Which Spelling Should You Use?
You should always use lambda. However, your audience still matters in how you explain it.
For US readers, keep it simple. Use lambda and move on.
For UK readers, do the same. No change is needed.
For global or professional writing, be extra careful. One mistake can reduce trust.
Moreover, exams, research papers, and code editors expect lambda. As a result, using lamda may look careless. Therefore, correct spelling protects your credibility.
In short, one rule works everywhere. Always write lambda.
