Erklärung
Because their yo forms don't end in -o (soy, estoy, voy, he, sé, doy), six verbs need their own subjunctive stems: sea, esté, vaya, haya, sepa, dé — then regular endings: seamos, vayan, sepáis.
Estar carries written accents on the stressed forms (esté, estés, estén) and dé takes one to distinguish it from the preposition de.
Everything else — including tener, venir, decir, conocer, the entire -go and -zco families — is covered by the yo-form recipe and is not, strictly speaking, irregular in the subjunctive.
