Homographs are words that are spelled the same regardless of pronunciation (they may be pronounced the same or differently). Homonyms are words that are both spelled and pronounced the same. Therefore a homonym is both a type of homograph and a type of homophone. To be correct I believe the Venn diagram should have one circle labeled homograph and the other labeled homophone. The intersection should be labeled homonym.
An Excessive Heat Warning is issued when heat indices are expected to reach at least 105 degrees, except at least 110 degrees over Delmarva and far southern New Jersey (Salem, Cumberland, Cape May, and Atlantic Counties).
According to the Indian Meteorological Department (IMD), a heat wave is qualified when air temperatures of at least 40 Â°C (104 Â°F) in the plains or greater than 30 Â°C (86 Â°F) in the hilly regions. For the IMD classification of heat waves, temperatures greater than 46 Â°C (114.8 Â°F) are considered and classified as severe heat waves.
