Other forms: uncloudedly
Anything unclouded is clear and transparent, whether it's your unclouded mind after a good night's sleep or an unclouded blue summer sky.
The adjective unclouded can be used to mean, literally "without any clouds," like a bright, cloudless sky. You can also use it for anything that's clear, rather than murky: "The lake was unclouded — you could see right down to the bottom." And the absence of gloom or darkness in a situation is yet another way to be unclouded: "Their lives were happy, unclouded by their neighbors' feuding."
