Note 262 — EL CAPITÁN VENENO[4]
Reading edition
¿Se puede entrar? May one enter? May I come in? This use of se is more and more felt as a nominative or subject: se ha dicho, it has been said, felt as one has said. Intransitive verbs started the fashion (or carried it on from the Latin type secutus est): está amándose being se está amando; and thus sound and use of intransitives with se became familiar through the very frequent verbs (intransitive) estar and ir, and spread till se, like que, has many shades of function.
