I recomend you to read: http://es.wikipedia.org/wiki/Subjuntivo

So, i try to explain in english... anyway is very dificult to explain the "Subjuntivo" For form that "subjuntivo" you must to take the first person to the presente de indicativo and put a termination like: Verbos -ar yo tú él, ella nosotros vosotros ellos, ellas -e -es -e -emos -éis -en Verbos -er/-ir yo tú él, ella nosotros vosotros ellos, ellas -a -as -a -amos -áis -an You can use the subjuntivo like a present o future, for example: Quiero que me acompañes ahora al museo. (presente) "I would like to go at the museum with you now" Quiero que vengas mañana conmigo al cine. (futuro) "I would like to go at the museum with you tomorrow" I hope you can understand and works with that and... sorry for me english!

Subjunctive in Spanish is a bit difficult as you don´t have so many forms in English and don´t have any knowledge of any other latin language, as French... I thing, it would help you to know that when you want communicate a desire, you normally use the Subjunctive. The example: I want you to come here. "Quiero que VENGAS". Second Person, Present, Subjunctive: Tú vengas (VENIR). Quiero que TENGA (yo), quiero que TENGA (él), ... TENGAMOS (nosotros), ... TENGAIS (vosotros), TENGAN (ellos). The question is not "I would like to"... but "I WANT TO"
