Dessert, with two S, is the sweet course at the end of a meal. Desert, with one, is arid land — or, as a verb with different stress, to abandon. The reliable trick: dessert has two S because you want two helpings, or because Sweet Stuff has two.
The core difference
One letter, three meanings, and two different pronunciations of the shorter spelling.
- dessert (di-ZURT) — the sweet course.
- desert (DEZ-ert) — arid land: the Sahara Desert.
- desert (di-ZURT) — to abandon: he deserted his post.
The stress does real work
Desert as a noun is stressed on the first syllable; as a verb, on the second — where it sounds identical to dessert. English does this with many noun/verb pairs (record, permit, conduct), and here it means the shorter spelling covers two words that sound different.
The phrase people get wrong
Just deserts takes one S. It is from an old noun desert meaning what you deserve — nothing to do with pudding, though "just desserts" appears constantly.
