Present subjunctive: the flipped endings
Take the yo form, drop -o, and flip the theme vowel: -ar verbs take e-endings (hable, hables), -er/-ir verbs take a-endings (coma, viva).

Erklärung
The recipe: start from the present yo form, remove the final -o, and add the opposite vowel's endings. Hablar → hablo → hable, hables, hable, hablemos, habléis, hablen. Comer → coma; vivir → viva.
Because the base is the yo form, irregularities propagate automatically: tengo → tenga, conozco → conozca, protejo → proteja, construyo → construya. Spelling rules apply at the boundary: busque, llegue, cruce.
Stem-changing verbs follow the boot in the subjunctive too (piense, pensemos; vuelva, volvamos), and -ir stem-changers raise their vowel in nosotros/vosotros: sintamos, durmáis, pidamos.
