Par. I62.] "IT" AS ANTECEDENT. 111
162 It would appear also to apply to(9) " It was at you that I laughed."
(10) " It was from you that I received this insult."
These sentences would appear to be for " It that
I laughed at was you," It that I received this
insult from was you."
It has been suggested that " it" is here the " Preparatory
it," and "that" a Conjunction, the meaning being " The
fact that I received this insult was owing to, or, from you."
But this does not seem to hold good for (9) " The fact that
I laughed was at you."
Of course however "it" is the Preparatory "it," and
"that" is a Conjunction in:
(11) " It was in the time of Julius Caesar that the Romans first
invaded Britain."
