Most of the time we use the verb "know" as an infinitve, correct? Like- "to know someone", right? So why do we use it as a gerund sometimes? What is the difference between "to know" and "knowing"? When do we use it as an infinitive and when do we use it as a gerund?
I believe it's a matter of (a) their position in the sentence and (b) their semantic content.Originally Posted by tilly
EX: To know him is to love him.
Adverbial phrases, wherein the words 'in order' has been omitted:
EX: (In order) to know what to do, you have to read the manual.
EX: You have to read the manual (in order) to know what to do.
EX: Knowing that s/he loves me makes me happy.
to-infinitives express a event that hasn't yet happened, whereas -ing words express an event that has happened. For example,
EX: To know him is to love him. (The person I am speaking to doesn't love him because s/he doesn't really know him)
EX: Knowing him is why I love him. (I know him, and that's why I love him.)
