Page "Colorless green ideas sleep furiously" Paragraph 4

The sentence can be given an interpretation through polysemy.

Both green and colorless have figurative meanings, which allow colorless to be interpreted as " nondescript " and green as " immature ".

The sentence can therefore be construed as " nondescript immature ideas have violent nightmares ", a phrase with less oblique semantics.

In particular, the phrase can have legitimate meaning too, if green is understood to mean " newly-formed " and sleep can be used to figuratively express mental or verbal dormancy.

An equivalent sentence would be " Newly formed bland ideas are inexpressible in an infuriating way.
