The word turgid is most commonly used in biology when discussing the process of osmosis.

The opposite of a turgid state is a flaccid state.

Turgidity is important for healthy plant cells, as it helps them maintain rigidness. In animal cells, by contrast, turgidity is not important because animal cells do not have cell walls and may burst due to the excess water.

The literary definition of turgid is bombastic, overblown and inflated. The word is most often used to describe someone or something that is overdone or exaggerated. For example, one might describe a lengthy action movie or an exhaustive autobiography as turgid. This usage is inspired by the biological definition of the word.
