Google is your friend.

One main difference between the two is the length of time. Ser is used for long/infinite time, and Estar is used for temporary time.

For example, "The man is handsome" uses Ser ("el hombre es guapo") because the man's handsomeness is pretty static.

Now, "The book is in the library" uses Estar ("el libro esta en la biblioteca") because the book may not always be in the library.

There are some other rules, like Estar is used when describing locations. I used to have a small card that had the differences in uses on it. I found it at Barnes and Noble for $3. Once I memorized it, gave it to a friend.

P.S. I wish this forum allowed you to type accented vowels.
psychodelic Reviewed by psychodelic on . Anyone Speak Spanish? I just received my test back from my Spanish teacher, and failed miserably. The part that kicked my butt the most was the use of "ser" and "estar" verbs. Not exactly sure when, how, or why to use them. Anyone got any tips or willing to help me out? Thanks *Gracias* Rating: 5
