• not personally
• vaguely
• remotely
• anyone who knows of
• via
• through
• regarding

• be aware of
• hear about

using *know from instead of *of when meaning external awareness; confusing with plain ‘know’ which implies personal acquaintance

hear of, be acquainted with, have heard/learned about – each carries a different connotation: hearing suggests passive receipt, being acquainted suggests more direct interaction

Learners may default to using simple ‘know’ without the preposition ‘of’, leading to misinterpretation as implying personal knowledge rather than mere awareness

• hear of
• be familiar with
• come across

'Know of' signals that one has been informed or aware through another source (e.g., media) but does not guarantee detailed familiarity, whereas 'know about' often indicates deeper understanding or experience

maintains politeness and modesty by avoiding claims of intimate acquaintance; useful in professional settings where over‑personalization could be perceived as presumptuous

‘Do you know of a good mechanic?’ – remember this pattern for asking/confirming general awareness without demanding specifics

This chunk is used to indicate awareness of someone or something without implying personal knowledge or experience. It is often used in contexts where the speaker wants to acknowledge information they have heard or read about, but cannot vouch for its accuracy or details.
