sliar

n. Person who tells lies that, technically speaking, are
not lies, by such means as quoting out of context or
otherwise leaving out information that would show a
statement he has made to be a gross misrepresentation.
"There is no record from the only grammar school in his
hometown or any other school of his time that Shakespeare
ever spent so much as a day in one." Left out: the fact that
we have no records of attendance from his hometown school
for years before and after he would have
gone to it, or from most other schools of his time.
