IPA: /ʌnˈdriːmd/
KK: /ʌnˈdrimd/
Referring to something that is beyond what one could imagine or think of; something that has not been dreamed or considered before.
The artist created an undreamed masterpiece that left everyone in awe.
Undreamed → It is formed from "un-" (meaning not) and "dreamed" (from Old English "drēam", meaning a dream or joyful noise). The word "undreamed" means not having been dreamed or imagined, suggesting something that has not yet been conceived in thought.
Think of something that has not been 'dreamed' ('drēam') or imagined at all — the 'un-' prefix means not.
