desirable

The word "desirable" is built upon the Latin verb desiderare, which meant to long for, miss, or feel the want of something, possibly originating from the phrase de sidere ("from the stars"), suggesting an astrological omen or a longing for what the stars might bring. The suffix -abilis was a productive Latin adjectival ending indicating capacity or worthiness. Combined in Old French and later Middle English, these elements formed "desirable," which literally means "worthy of being longed for." Over time, the meaning broadened from intense longing to encompass anything considered attractive, advantageous, or worth having.
