Is Logarithm in the Dictionary?

As an eminent mathematician, I have often been asked by my students and colleagues whether the term ‘logarithm’ is a word that can be found in the dictionary. It might come as a surprise to some, but the answer is not a simple ‘yes’ or ‘no’.

What is a Logarithm?

Before we delve into the question at hand, it is important to understand what a logarithm is. In basic terms, a logarithm is the exponent to which a base number must be raised to produce a given value. For example, in the equation x = log2 8, the base is 2, the exponent is x, and the value is 8. Solving for x gives us x = 3.

Logarithms were first introduced by mathematician John Napier in the early 17th century, and they have since become an important tool in many fields of science and engineering. They are particularly useful for dealing with very large or very small numbers, as they allow us to condense the scale of our calculations.

The Dictionary Definition of ‘Logarithm’

Now, getting back to the question at hand, let’s consider what the dictionary has to say about the term ‘logarithm’. Most standard English dictionaries do include an entry for ‘logarithm’, which is typically defined as:

“The power to which a number must be raised in order to produce a given value.”

Some dictionaries may include additional information or definitions, such as the historical context and origin of the term.

The Controversy Surrounding ‘Logarithm’

However, there are some who argue that ‘logarithm’ is not a true word as it does not conform to certain linguistic rules. For example, it is not derived from a Latin or Greek root word, and it does not have a regular plural form. Additionally, some dictionaries may only classify ‘logarithm’ as a technical term rather than a standard English word.

Despite this controversy, it is important to note that the use of ‘logarithm’ as a term in mathematics and science is widely accepted and recognized. It has a well-defined meaning and function within these fields, and its significance cannot be denied.


So, is ‘logarithm’ in the dictionary? The answer is yes, but with some caveats. While it may not conform to certain linguistic rules and may be classified as a technical term, it is widely recognized and serves an important purpose. As mathematicians and scientists, we must continue to use and appreciate the power of logarithms in our work, regardless of their classification in the dictionary.
