Notes on asegurarse in the Present Subjunctive
Asegurarse is regular in the present subjunctive. It follows the pattern of other '-ar' verbs: take the 'yo' form of the present indicative (me aseguro), drop the '-o' (me asegur-), and add the opposite vowel endings (-e, -es, -e, -emos, -éis, -en). Remember the reflexive pronoun goes before the verb.
