Exploring the Usage of 'Probable' vs 'Likely' in English

In the English language, expressing a likelihood or probability is a common necessity, whether you're conveying something as sure as the sun rising or as uncertain as the weather. Two terms, 'probable' and 'likely,' are often used interchangeably but have slightly different connotations. This article delves into when and how to use each term effectively in your writing and speech.

The Formality and Coverage of 'Probable'

'Probable' is a term that conveys a higher level of certainty than 'likely.' It is frequently used in formal and academic contexts. For instance, if you are absolutely certain of something but don't want to assert it with complete confidence, you might use 'probable.' Here's how to use it in a sentence:

Example: It is probable that I would use the word when I was fairly sure I would use it, but not certain.

Commonality and Naturalness of 'Likely'

'Likely,' on the other hand, is more common and natural in everyday conversation. It is less formal and is typically used to express a higher degree of likelihood than 'probably.' When you are unsure but have reasons to believe something is more likely, 'likely' is your go-to term.

Comparing 'Probable' and 'Likely'

Several questions may arise when comparing 'probable' and 'likely.' For example:

Question 1: Is it more natural and common to say 'It is probable that it will happen' or 'It is likely to happen?' The answer is: it is more natural and common to say 'It is likely to happen.' Question 2: Is it more natural and common to ask 'How probable is it?' or 'How likely is it?' Again, the more natural and common phrase is 'How likely is it.'

Examples in Context

When using these terms, consider their context. Here are some examples:

Formal Statement: In the next election, it is probable that DJT will win. (This is more formal and less common in everyday conversation.) Daily Conversation: It is likely that DJT will win the next election. (This is more natural and common in everyday conversation.) Planning and Weather: I haven’t finalized any plans yet, but I will most likely go to the beach tomorrow. (Using 'likely' is more natural and common.) Weather Forecast: Today will be cloudy, and scattered showers are likely. (Likely is the better choice here.)

Examples and Substitution

Here are some examples of using 'likely' in sentences, along with their substitution with 'probably':

Example: It is likely to rain tomorrow. (Equivalent: 'It is probably going to rain tomorrow.' Both are correct, but 'likely' is more natural.) Example: The dog will likely come home when he is hungry. (Equivalent: 'The dog will probably come home when he is hungry.')

Definition and Context of 'Likely'

Examining the definition of 'likely' can help you understand its nuanced usage. The term 'likely' generally means 'something that has the best odds of being a certain way if the current situation remains as it is now.' Here are some example sentences with their definitions:

There are black clouds, so it's likely to rain. (It is highly probable that it will rain due to the presence of clouds.) John has years of experience in education, so he's a likely candidate for the teaching job. (He is the most probable candidate due to his experience.)

Further examples:

If he is a liar, then it is likely he is a thief or worse. (Given the current information, it is highly probable that he might be a thief or more sinister.) She said that I am likely to take a long walk on a short pier. (Based on current circumstances, it is highly probable that I will do so.) We will likely see rain if the weather pattern holds. (Given the current weather conditions, it is highly probable that it will rain.) As the dead walked and the ravenous armies of zombies multiplied, humanity was likely to become extinct. (Given the current situation, it is highly probable that humanity will face extinction.)

In conclusion, while 'likely' and 'probable' serve a similar function, their usage varies based on the formality of the context. 'Likely' is more natural in everyday conversation, while 'probable' is more formal. Understanding the nuances can help you express your likelihoods and probabilities more accurately and effectively in both formal and informal settings.
