Without boundaries or limits; not confined or restricted; boundless or infinite.
From confine plus the suffix -less, meaning 'without.' This construction follows the standard English pattern of adding -less to create antonyms or negations.
The Romantic poets of the 1800s were obsessed with 'confineless' space and nature—they saw limitlessness as where the human soul could finally be free from society's rules, which is why so many of them climbed mountains and stared at oceans.
