Type that is photographically or electronically slanted at an angle. Can be accidental or on purpose, e.g. to emulate unavailable italics, or to further increase the angle of an italic style. Slanted letterforms typically suffer from a lack of optical correction. AKA fake italic or oblique.
Note that some typeface families (especially sans serifs) have oblique styles instead of “true” italics. These don’t exhibit traditional calligraphic characteristics (such as the monocular ‘a’, the rounded ‘e’, or the ‘f’ with descender), but, unlike slanted type, are usually optically corrected.
