Note 266 — EL CAPITÁN VENENO[4]
Reading edition
empeñado usted en, (because) you insisted on (sitting up to watch with her): verbs compounded show a tendency to echo the prefix (unless the verb is used for some commoner verb of a different construction, e.g. consentir en or convenir en under the influence of venir en, quedar en): dejar de hablar, to cease from speaking; contar con, count on; insistir en; acostumbrarse a; cumplir con, comply with—cumplir formerly was used much more without con as equivalent to hacer; now it tends to become a special verb with con (cumplir con sus deberes, comply with one's obligations). Before que of the dependent clause the preposition is very exacting. Cf. for use of prepositions, English depart from, agree to, dismiss from, admit to, enter in, etc.
