How to use "be aware of"

What Does "be aware of" Mean?

The expression be aware of is a common English collocation used to indicate that someone has knowledge, consciousness, or realization of a specific fact, situation, or person. It suggests a state of being informed or mindful rather than a sudden action of noticing.

• Meaning: To have knowledge or perception of a situation or fact.
• Compositionality: The meaning is compositional; it combines the linking verb "be" with the adjective "aware" and the preposition "of."
• Register: This expression is neutral to formal. It is equally appropriate in casual conversation, academic writing, and professional warnings.

How to Use It

• Grammatical pattern: The structure is [be] + aware + of + [noun/pronoun/gerund].
• Typical objects: It is frequently followed by abstract nouns (risks, consequences), physical hazards (surroundings, predators), or social cues (hierarchy, jealousy).
• Separability: Because this is an adjective-preposition combination and not a phrasal verb, the components cannot be separated by an object. You cannot say "be aware the risk of."
• What sounds unnatural: Using the wrong preposition is the most common error. Phrases like "aware about" or "aware to" are grammatically incorrect in standard English.

FAQs

Can the words in the phrase be aware of be separated by other words?
