Saber Present Subjunctive Practice

Saber (to know (facts, skills)) in the present subjunctive: 14 free exercises with an explanation after every answer, plus the full conjugation table.

14 exercisesIrregularB1 – B2 level
IWhat to watch for

Saber has a fully irregular present subjunctive built on the stem sep-: sepa, sepas, sepa, sepamos, sepáis, sepan. None of these look like the infinitive, so they simply have to be memorized as a set.

The trap is reaching for the indicative sabe or the odd yo form sé after a trigger — quiero que or ojalá demand sepa and sepamos instead. Remember saber means to know a fact or to know how to do something, so 'sepa nadar' is know how to swim, not know a person.
