Flipping through a Sunday grid, I often notice the way a clue like "omnipotent" is handled feels like a tiny etiquette test between setter and solver.
For easier, American-style puzzles you'll usually see it clued very directly — synonyms like 'almighty' (8) or 'all-powerful' used as straightforward definitions. Editors are careful about length, so you might instead get 'all-powerful deity' which hints at 'GOD' or 'THE LORD' in shorter slots. In themed puzzles the concept can be disguised: an entry might be split across theme answers, hidden in a long phrase, or reinterpreted as a pop-culture nod.
In British-style cryptics the setter gets playful. A clean anagram is common: 'Potent, I'm no (10)' is a neat cryptic that literally scrambles 'POTENT IM NO' into 'OMNIPOTENT'. Other cryptic devices include hidden-word clues, whimsical surface readings, or charade clues that build the word from Latin roots like 'omni-' (all) + 'potent' (powerful). I love seeing that mix of linguistic craft and crossword fairness — it makes solving feel like a small victory every time.
