This quiz is for primary and secondary pupils learning to take a sentence apart, and for adults who want to brush up on grammar terms. A part of speech tells you what kind of word it is, as a dictionary would; its role tells you the job it does in a particular sentence.
The first questions use short, everyday sentences; later ones deal with objects, complements and words that change category depending on where they sit. Tip: to find a word’s role, ask the verb a question (who did it? did what? to whom?) and try swapping the phrase for a pronoun.
