If you would rather die than have to learn more irregular verbs, today is your lucky day. The first letter of the irregular verbs of the Spanish Subjunctive happens to spell DIES.
You will have to add an extra S to make this mnemonic work.
D ar
I r
E star
S aber
S er
Haber is also irregular in the Subjunctive but I couldn't make it fit into the death theme that I became so attached to. Besides, you should probably know by know that haber is always doing something crazy. Just assume it is irregular unless notified otherwise.
