The English language, rich and versatile, often presents subtle challenges, especially when it comes to prepositions. One such area of confusion arises with the phrases “compare to” and “compare with.” While seemingly interchangeable, these phrases carry distinct nuances that can alter the meaning of your sentences. Understanding when to use “compare to” versus “compare with” is crucial for precise and effective communication. Let’s delve into the subtle yet significant differences between these two common expressions.
Dissecting “Compare To” and “Compare With”
Grammar authorities and style guides have long offered insights into the proper usage of “compare to” and “compare with.” Historically, a distinction has been drawn based on the nature of the comparison being made – whether highlighting similarities, differences, or both.
“Compare To”: Highlighting Likeness and Analogy
The phrase “compare to” is typically employed when you aim to point out resemblances or similarities between two things that are essentially of different categories or orders. It’s about drawing an analogy or illustrating a likeness, often for explanatory or poetic effect. Think of it as saying something is like something else in a particular aspect.
For example, consider the classic line: “Shall I compare thee to a summer’s day?” Here, Shakespeare isn’t suggesting a summer’s day and his beloved are of the same category. Instead, he uses the familiar and pleasant image of a summer’s day to illuminate certain qualities of his love. This is a quintessential use of “compare to” – establishing a figurative link.
Another example: “Life has often been compared to a journey.” Life and a journey are not the same type of entity. The comparison serves to highlight the analogous aspects – stages, challenges, and progression – inherent in both concepts.
“Compare With”: Analyzing Similarities and Differences Within the Same Category
In contrast, “compare with” is generally used when you are placing two things of the same general category side-by-side to examine both their similarities and differences. This is about a more analytical comparison, often with the goal of evaluating or contrasting.
For instance: “Let’s compare the performance of this year’s model with last year’s model.” Here, we are comparing two models of the same product, likely looking at specifications, features, and improvements. The focus is on a detailed examination of both commonalities and distinctions within a shared framework.
Another example: “Economists often compare the US economy with the European economy.” Both are large-scale economies, making the comparison meaningful for understanding relative strengths, weaknesses, and economic policies.
Diverging Opinions and Modern Usage
While the traditional distinction provides a helpful guideline, language is dynamic, and usage evolves. Some modern style guides acknowledge a degree of overlap and flexibility, particularly in informal contexts.
One perspective, as noted in Good Grammar Made Easy, suggests that in contemporary Standard American Written English (SAWE), either “compare to” or “compare with” can be used to mean both:
- (a) Likening: “You can’t compare a bicycle to [or with] a car.” (Highlighting the difference in category and capability).
- (b) Observing Similarities and Differences: “Comparing a bicycle to [or with] a car, you notice differences in speed and environmental impact.” (Analyzing features within a comparative context).
However, it’s crucial to note the caution raised: many readers still adhere to the more traditional distinction and may find the interchangeable use jarring or imprecise, especially in formal writing.
Choosing the Right Phrase: Clarity and Context
So, how do you decide whether to use “compare to” or “compare with”? Consider your intent and your audience:
-
For Analogy and Likeness (Different Categories): When you aim to illustrate a point by drawing a parallel between fundamentally different things, “compare to” is generally the more precise choice.
-
For Analysis and Contrast (Same Category): When you are examining items within the same category to highlight both similarities and differences, “compare with” is typically more appropriate.
-
Context Matters: In less formal settings, or when aiming for a more conversational tone, using “compare to” or “compare with” interchangeably might be acceptable, especially when the context makes your meaning clear. However, in formal writing, academic work, or professional communications, adhering to the traditional distinction often enhances clarity and avoids potential misinterpretations.
Conclusion: Precision in Comparison
While the lines between “compare to” and “compare with” may blur in modern usage, understanding their traditional nuances remains valuable. By recognizing the subtle difference – “compare to” for analogy and likeness, and “compare with” for analysis and contrast – you can wield these phrases with greater precision and ensure your comparisons are both clear and impactful. Whether you are crafting a poetic metaphor or a detailed analytical report, choosing the right phrase will contribute to the effectiveness and sophistication of your communication.
