Careful Words

contagious (adj.)

The chariest maid is prodigal enough,

If she unmask her beauty to the moon:

Virtue itself'scapes not calumnious strokes:

The canker galls the infants of the spring

Too oft before their buttons be disclosed,

And in the morn and liquid dew of youth

Contagious blastments are most imminent.

William Shakespeare (1564-1616): Hamlet. Act i. Sc. 3.
