To vs. Too – Which is Correct?

When expressing an excessive degree, like with the adjective ‘small,’ the correct word to use is too. The phrase ‘too small’ indicates something is excessively undersized, while ‘to small’ is grammatically incorrect in this context if you intend to convey excess. ‘To’ functions as a preposition or part of an infinitive, whereas ‘too’ is an adverb of degree or inclusion.

To or Too – Which is Correct?

The confusion between “to” and “too” is common due to their identical pronunciation. However, their grammatical roles and meanings are distinct, especially when paired with an adjective like “small.”

To is primarily a preposition (indicating direction, purpose, or relationship) or an infinitive marker (forming the base form of a verb, e.g., “to run”). It does not function as an intensifier or an adverb of degree.

Too is an adverb with two main uses:

1. To mean “excessively” or “more than enough,” often placed before an adjective or another adverb (e.g., “too small,” “too quickly”). This is the meaning relevant to the phrase “too small.”
2. To mean “also” or “in addition” (e.g., “I want some, too”).

Therefore, to correctly express that something is excessively small, you must use too small.

The Best Trick to Remember the Difference

A powerful trick to remember the difference is to think of the extra ‘o’ in “too.” If you mean “excessively” or “more than enough,” the word “too” has an extra ‘o’, just like the words “extra” or “excessive.” If you can replace “too” with “excessively” or “also,” then “too” with the double ‘o’ is the correct choice. If not, and you’re indicating direction or forming an infinitive, then “to” is correct.

Word	Part of Speech	Meaning Relevant to “Small”	Example
to	Preposition / Infinitive Marker	Indicates direction, purpose, or forms infinitives (not used to modify adjectives for degree).	“I need to adjust the setting to small.”
too	Adverb	Excessively; more than enough.	“The shoes are too small for me.”

How to Use To

The word “to” is one of the most versatile words in the English language, primarily functioning as a preposition or an infinitive marker. It connects words and ideas, indicating direction, purpose, relationship, or forming the base of a verb phrase. Understanding its roles is key to avoiding confusion with “too.”

As a preposition, “to” often expresses movement towards a place, a recipient, a limit, or a comparison. It can also indicate purpose or relationship.

Example 1 (Direction): “She walked to the store.”

Example 2 (Recipient): “Please give this book to him.”

Example 3 (Purpose/Relationship): “We need a solution to this problem.”

As an infinitive marker, “to” precedes the base form of a verb, creating an infinitive phrase that can function as a noun, adjective, or adverb.

Example 4 (Infinitive): “They decided to leave early.”

Example 5 (Infinitive as adjective): “I have a lot of work to do.”

While “to” is not used to express excessive degree, it can appear before “small” in specific, less common contexts where “small” functions as a noun or part of a fixed phrase, or when indicating a transition *to* a small state. For instance, “adjust the setting to small” means to change the setting *to* the small option, not that the setting itself is excessively small.

Etymology of the word To

The word “to” has ancient Germanic roots. It comes from Old English tō, which meant “in the direction of, for the purpose of, in addition to.” Its origins can be traced back further to Proto-Germanic *tō and ultimately to Proto-Indo-European *do-, meaning “to, toward, at.” Over centuries, its usage evolved to encompass its various prepositional and infinitive roles in modern English.

How to Use Too

“Too” is an adverb that conveys additional meaning in two primary ways: indicating excess or indicating inclusion. Its use as an intensifier, meaning “excessively,” is where it often gets confused with “to,” especially when modifying adjectives like “small.”

When “too” means “excessively” or “more than enough,” it typically precedes an adjective or another adverb. This is its role in “too small.” It suggests that the degree of the adjective is beyond what is desirable, appropriate, or possible.

Example 1 (Excessive degree): “The jacket is too small for me; I can’t even zip it up.”

Example 2 (Excessive degree with another adverb): “You are driving too fast.”

Example 3 (Excessive degree with an adjective): “The coffee is too hot to drink right now.”

When “too” means “also” or “in addition,” it usually appears at the end of a sentence or clause, separated by a comma. In this usage, it functions similarly to “as well.”

Example 4 (Inclusion): “I want a slice of pizza, too.”

Example 5 (Inclusion): “She decided to join the club too.”

Etymology of the word Too

The word “too” shares its etymological roots with “to.” It also derives from Old English tō. However, “too” developed a distinct meaning from “to” by emphasizing the idea of “in addition” or “excessively.” This adverbial sense of “too” began to emerge in Middle English, distinguishing itself from the prepositional and infinitive uses of “to.” The spelling with the double ‘o’ became standard to differentiate it visually from “to” and “two” around the 16th century.

Related Concepts

Understanding broader grammatical concepts can illuminate why “to” and “too” function differently and why their misuse is so common.

• Homophones: These are words that sound alike but have different meanings and spellings. “To,” “too,” and “two” are classic examples of homophones. Their identical pronunciation is the primary source of confusion.
• Adverbs of Degree: Adverbs of degree, like “too,” “very,” “extremely,” or “quite,” modify adjectives or other adverbs to indicate the intensity or extent of a quality. “Too” specifically implies an excessive or undesirable degree.
• Prepositions: Prepositions are words (like “to,” “in,” “on,” “at”) that show the relationship between a noun or pronoun and other words in a sentence. “To” is frequently used as a preposition, indicating direction, purpose, or comparison.
• Parts of Speech: Recognizing the distinct parts of speech—preposition, infinitive marker, and adverb—for “to” and “too” is fundamental. Each part of speech has specific rules governing its placement and function within a sentence.

Frequently Asked Questions

Question 1: Why is “to small” incorrect when meaning “excessively small”?
“To” is a preposition or an infinitive marker, not an adverb of degree. It cannot modify an adjective like “small” to indicate an excessive amount. Only “too,” functioning as an adverb, has the meaning of “excessively.”

Question 2: Can “to” ever be used before “small”?
Yes, but in different contexts. For example, you might say, “Set the dial to small” (meaning to the small setting), or “The project was reduced to small pieces” (meaning into small pieces). In these cases, “to” is a preposition indicating direction or transformation, not an intensifier of “small.”

Question 3: What’s the difference between “too small” and “very small”?
Both “too” and “very” are adverbs of degree, but they convey different implications. “Very small” simply states that something is small to a high degree. “Too small” implies that something is small to an undesirable or problematic degree, often suggesting a negative consequence or a need for change. For instance, “The car is very small” is a descriptive statement, while “The car is too small” implies it’s insufficient for its purpose.

Conclusion

Mastering the distinction between “to” and “too” is crucial for clear and precise communication. While they sound identical, their grammatical functions are entirely separate. Remember that “too” with its extra ‘o’ signifies “excessively” or “also,” making “too small” the correct phrase when expressing an undesirable degree of smallness. “To” serves as a versatile preposition or infinitive marker, guiding us through sentences but never intensifying an adjective. A consistent application of this knowledge will enhance your writing and speaking, projecting an image of careful attention to detail.
