someday
UK: ˈsʌm.deɪ | US: ˈsʌm.deɪ
adv. at some unspecified time in the future
adv. eventually; one day
The word "someday" is a straightforward compound of "some" (indicating an unspecified or indefinite quantity/time) and "day" (referring to a 24-hour period). It emerged in Middle English, combining these two common words to express the idea of an indefinite future time. The logic is intuitive: "some" softens the specificity of "day," creating a vague but hopeful reference to the future. Unlike more complex etymologies, this compound retains its literal meaning without significant semantic shift.
Someday, I hope to travel the world.
She dreams of becoming a famous writer someday.
Maybe someday we’ll meet again.
He promised to repay the money someday.
Someday, technology will solve these problems.
