How Ser or Estar Affects Spanish Adjectives

How Ser or Estar Affects Spanish Adjectives Although ser and estar both mean to be, to the native Spanish speaker they dont mean the same thing. As a result, some adjectives can change in meaning depending on whether theyre used with ser or estar. One common example is listo. When used with ser, it typically refers to being clever or intelligent: El mono es listo, flexible e innovador. (The monkey is clever, flexible and innovative.) But when used with estar, it often means ready: Dice que no est lista para convertirse en madre. (She says she isnt ready to become a mother.) One reason for the change in meaning is because ser is typically (although there are exceptions) used with enduring or innate qualities - and in the case of listo, you might think of clever as similar in meaning to the idea of always ready. Following are some other adjectives that you can think of as changing in meaning depending on which form of to be they are used with.
