Did you know?

Changing the pitch, tone, or loudness of our words are ways we communicate meaning in speech, though not on the printed page. A rising inflection at the end of a sentence generally indicates a question, and a falling inflection indicates a statement, for example. Another way of inflecting words is by adding endings: -s to make a noun plural, -ed to put a verb in the past tense, -er to form the comparative form of an adjective, and so on.

Synonyms

• angle
• arc
• arch
