subscribir

Subscribir is not a standard form in modern Spanish. The normative verbs are suscribir and suscribirse, with suscribir as a transitive verb (to subscribe to something or to sign/endorse a document) and suscribirse as the reflexive form (to subscribe oneself to a service, newsletter, channel, etc.). The appearance of subscribir is typically considered a misspelling or a nonstandard variant rather than a separate correct conjugation.

Etymology and usage notes: Both suscribir and suscribirse derive from the Latin subcribere, and both have circulated in Spanish through historical forms that favored suscribir in preference to a hypothetical subscribir. In practice, subscribir is rarely accepted in contemporary dictionaries and is generally avoided in formal writing. Some occurrences can be traced to influences from other languages, such as Portuguese subscrever, or to direct calques from English subscribe, especially in informal contexts or brand names.

Practical guidance: When you need to express subscribing in Spanish, prefer suscribir or suscribirse, depending on whether the verb is transitive or reflexive. Examples: Me suscribí al boletín. Quiero suscribirme a este canal. Suscribí el contrato. Avoid subscribing as a standalone verb in standard Spanish, and replace with suscribir or suscribirse to ensure correctness.
