# Likelihood vs. Likeliness: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 27, 2024

**Likelihood refers to the probability or chance of something happening, while likeness describes the state or quality of being similar or alike.**

## Key Differences

Likelihood and likeliness are both nouns that describe the chance of something occurring. However, likelihood is more commonly used in modern English, particularly in statistical or probabilistic contexts, to denote the probability or chance of an event. Likeliness, though similar in meaning, is less frequently used and can sometimes be seen as more archaic or literary.

The word likelihood implies a quantitative assessment of probability. It is often used in scientific, mathematical, or logical discussions where the probability of events is calculated or estimated. Likeliness, on the other hand, while also referring to the probability of something happening, is less likely to be used in a technical or mathematical context and more in general language.

In terms of usage, likelihood is often found in academic and professional writings. It's a preferred term in statistics and research for discussing the odds or chances of certain outcomes. Likeliness is more colloquial and might be used in everyday conversation or in literary contexts, where the formality and precision of likelihood are not required.

Both likelihood and likeliness can be modified by adverbs to indicate the degree of probability (e.g., high likelihood, low likeliness). However, the use of likelihood in such constructions is more prevalent, reflecting its wider acceptance and usage in contemporary English.

Likelihood and likeliness are synonyms and interchangeable in many contexts, likelihood is the more commonly used term, especially in formal and technical writing. Likeliness maintains a presence in the language but is less prevalent and tends to appear in more general or less technical discussions.
