Damasked

Part of speech: noun

Source: English Oxford Living Dictionaries

Definition: A rich, heavy silk or linen fabric with a pattern woven into it, used for table linen and upholstery.

Found in Shakespeare’s Sonnet 130, line 5: My Mistress’ Eyes Are Nothing Like The Sun

Knowing the definition of damasked helped me to understand the line fully. A first I looked at ‘ I have seen roses damasked, red and white ‘ like what does that mean ? But now I see that the speaker is comparing his wife’s cheeks to the beauty of a tablecloth.
