漠 desert

Welcome BACK TO the desert, motherfucker! All us scorpions and vultures missed you!

Addicts need opium like desert travelers need water.

desert ★★★☆☆
砂 (sand) + 漠 (desert) = 砂漠 (desert )

vague ☆☆☆☆☆
漠 (desert) + 然 (nature) = 漠然 (vague)

vague, obscure: unlike the related term 紛らわしい　（まぎらわしい）、漠然 isn't intentionally misleading - it has more the sense of a vague old memory you can't picture clearly even if you try.
