Sentence examples for only one small from inspiring English sources

No, 'only one small' is not a grammatically correct phrase and it would not be considered standard usage in written English.
The word 'only' is often used to qualify the noun or verb that follows it, but it cannot stand alone in a sentence. It would need to be followed by a noun or a verb. For example: "There was only one small cookie left in the jar." In this sentence, 'only one small' is used to describe the cookie, so it needs to be followed by a noun (cookie). Another example: "He could only take one small step at a time." Here, 'only one small' is used to qualify the verb 'take', so it needs to be followed by a verb (step). In both of these examples, the usage of 'only one small' is correct because it is followed by a noun or a verb. However, using it as a standalone phrase like "Only one small was left behind." would not be correct grammar. It would need to be rephrased as "There was only one small thing left behind."
