"Haber" and all of its conjugations are used for state that someone/something make presence, it is used in all tenses. That doesn't mean possession per se, do not imply that you own that thing or has an owner. ex. "Hubo" un bunker debajo de esa iglesia. (there was a bunker under that church) ¡Mira! "Hay" un colibrí volando sobre las rosas (look! there's a honeybird flying over the roses) En el futuro "habrá" coches que puedan volar. (in the future, it will be flying cars) On the other hand, "Tener" is a verb that implies belongings in terms of things, it also could be a disease, condition, skill, pet, children, etc., that someone has/had/going to have. Ex. Cuando era un niño "tuve" una mascota llamada Perla (when i was a kid, i had a pet called perla) No puedo correr, porque "tengo" asma. (i can't go running beccause i have asthma) Cuando me case, tendré dos hijos..(once i get married, i'm planing to have 2 kids)

Maybe this will help. Haber is a auxiliary verb. Hay carros en la calle. Their are cars in the street. Hay is the form of haber. He estudio. I have studied. He Tener is the possessive form of to have. Tengo un carro rojo. I have a red car. http://spanish.about.com/od/usingparticularverbs/a/haber_intro.htm

Hello... i´m William form Colombia and i´m interested to speak english. The diference between haber Vs tener is that "haber" is when there is a situation... "nosotros HEMOS trabajado mucho" and "tener" have two meanings.... 1 example: "nosotros TUVIMOS o TENEMOS que trabajar mucho" this part es very similar to the firts one and the other is " nosotros TENEMOS un carro antiguo" is for say that you have a thing. I wait that you understan me.. bye
