In the sentence ‘Your brain is protecting you from threats it believes are present,’ the question arises whether a relative pronoun is missing. Let’s break it down to understand if there’s any omission of a relative pronoun and explore how this affects the structure of the sentence.
Understanding Relative Pronouns
Relative pronouns are words like ‘who,’ ‘whom,’ ‘which,’ ‘that,’ and ‘whose’ that link a relative clause to the main clause of a sentence. In English, relative clauses provide additional information about a noun mentioned earlier in the sentence. In the sentence we are analyzing, ‘it believes’ refers to the brain, which is the subject of the main clause.
The relative clause in this sentence is ‘it believes are present.’ This clause provides more information about the noun ‘threats.’ The relative pronoun here is implied, but it is not explicitly stated. The structure is understood to be something like: ‘Your brain is protecting you from threats that it believes are present.’
Is a Relative Pronoun Omitted?
Yes, a relative pronoun is implied in the sentence, though not explicitly written. The word ‘that’ is commonly used in relative clauses to connect a noun with a further explanation, as in ‘threats that it believes are present.’ In informal speech or writing, native speakers often omit the relative pronoun ‘that’ in such cases, especially when it does not change the meaning of the sentence.
So, while the sentence does not overtly display the relative pronoun, the sentence structure remains grammatically correct and clear. The omission of ‘that’ in this context is a common feature in English, especially when the meaning is still clear without it.
Grammatical Structure of the Sentence
The full form of the sentence could be written as: ‘Your brain is protecting you from threats that it believes are present.’ In this construction, the relative pronoun ‘that’ is explicitly present, connecting ‘threats’ with ‘it believes are present.’ In both versions, the sentence conveys the same meaning. The omission of ‘that’ does not impact the sentence’s meaning but is rather a stylistic choice commonly used in English.
This phenomenon of omitting relative pronouns occurs frequently in English, especially in casual speech or when the relative pronoun is not essential to understanding the sentence’s meaning. Understanding when and why this happens can help improve your grasp of English sentence structures.
Conclusion
The sentence ‘Your brain is protecting you from threats it believes are present’ does indeed omit a relative pronoun (‘that’). However, this omission is perfectly acceptable in English grammar, especially in spoken language or informal contexts. The meaning remains clear, and the sentence is grammatically correct without the explicit use of the relative pronoun.
