A blank verse is a literary device written in iambic pentameter (a metrical line used in English poetry and verse drama) with regular metrical but with unrhymed lines. This means it consists of five feet, each foot being iambic, meaning two syllables long, one unstressed followed by a stressed syllable.
Intolerant means not being able to accept differences in opinions or other ideas, or someone who is unable to handle something. This includes being unable to endure something.
