What is a Gerund?
I was watching lesson 1.11 (ser vs. estar) and it was saying a progressive action = estar + gerund (-ing).
Can someone please tell me what a gerund is?
Thanks! =)

A gerund in English is a verb ending in -ing which behaves like a noun, eg. I like watching TV.
Spanish does not have anything like the English gerund. There is something called "gerundio", but it is like the present participle in English (ie. the -ing for in "I am singing.")
Here's one:

Oh, wait... that's a gerbil. Nevermind. ![]()
Listen to Lazarus.
The words "gerund" and "gerundio" are false cognates. As was explained, a gerund in English is a verb ending in -ing that's used as a noun - I like running. When a verb ending in -ing is used as part of a compound verb tense like the present progressive it is a present participle - The bulls were running down the street.
Spanish doesn't have that. A gerundio is just a verb ending in -ando or -iendo, and it is almost always used as part of a progressive verb tense - Los toros estaban corriendo por la calle. It cannot be used as a noun. To use a verb as a noun, you use the infinitive - Me gusta correr. Me gusta corriendo is just wrong.

"always"? The gerundio has other (perhaps, less frequent) uses, as well. It can also be used as an adverb (and, according to Lazarus [whom I am not inclined to doubt] as an adjective). However (more to the point) it cannot be used as a noun (as it is in English).
Lazarus explains it very well. I will add a little tidbit from my "501 spanish verbs" book that helped me. The English gerund noun ends in _ing and is used as "Reading is good" which is the subject of the verb is. As a present participle it is used as "While reading, the boy fell asleep". In Spanish the present participle form as a noun to serve as a subject you would use the infinitive as "Leer es bueno", Reading is good. Using the true Spanish present participle you would use the endings _ando & _iendo to form the verb and use it with the progressive present tense forms which is a whole different chapter altogether.
