Why Dry Becomes Dries but Play Becomes Plays
Dries is the third-person form of dry. The y changes to ies only when a consonant comes before it, which is a rule with no exceptions.
Dries is the third-person singular of *dry*. The spelling rule is one of the few in English with no exceptions worth learning: if a consonant precedes the y, it becomes *ies* — dry gives dries, carry gives carries, city gives cities. If a vowel precedes it, the y stays — play gives plays, key gives keys, monkey gives monkeys. The same rule governs *-ed* endings: dried, carried, but played.

- Dried — the past. *Dried fruit.*
- Drier — more dry, or a machine. *A hair drier.*

- Proper names are exempt: two Marys, not two Maries

From *dry*, Old English *dryge*, from a Germanic root related to *drought* and *drain*.
Is it drier or dryer?
Drier is the comparative adjective. Dryer is the usual spelling for the machine, though both appear.
Why do some words keep the y?
Because a vowel comes before it. Play, key and monkey all have a vowel before the y, so they simply add s.
