how do you put irregular verbs into subjunctive form?

Question

anonymous · Answer

There are exceptions, but often you use the singular first person (yo) conjugation, then replace the -o at the end with the appropriate subjunctive ending.

Example: tener --> tengo (first person singular present) --> tenga (subjunctive)
Espero que (ella) tenga el libro.  I hope she has the book.

Necesito que tengas cuidado.  I need you to be careful.

Example: conducir --> conduzco --> conduzca (subjunctive)
Quiero que conduzcas con mas cuidado.  I want you to drive more carefully.

Other irregulars include ser (--> sea) and ir (--> vaya)
