Toward the clouds or the sky; moving in the direction of the clouds (British variant).
From 'cloud' plus '-wards' (Old English directional suffix, a variant of '-ward'). The '-wards' ending became the British preference (like 'towards' vs. 'toward') while American English favors '-ward'.
The '-wards' vs. '-ward' split is a fascinating British-American divergence: British English added an '-s' to words like 'toward/towards,' 'backward/backwards,' and 'forward/forwards,' but Americans kept them singular, and now the British forms are considered slightly more formal or poetic.
