A rare or technical term meaning to cause to evaporate or to remove moisture from something.
From de- (Latin prefix meaning 'away' or 'down') + evaporate (from Latin 'e-' out + 'vapor' steam). This combines the reversal prefix with the evaporation process.
This word is so uncommon that most dictionaries don't list it, but it represents an interesting pattern in English where adding 'de-' to verbs can reverse or intensify their meaning—similar to how 'de-frost' means to thaw something frozen.
