IPA: /ˈdaɪərɪst/
KK: /daɪərɛst/
The most serious or urgent situation or condition.
The direst consequences of climate change could affect millions of people.
Direst → It is formed from "dire" (from Old French *dire*, meaning to say or tell) and the superlative suffix "-est" (meaning most). The word "direst" means the most serious or urgent, as if it is something that must be said or told urgently.
Think of something that needs to be 'said' or 'told' urgently ('dire') — and when it's the 'most' urgent, that's what 'direst' means.
