A tenor de este horario autorizado, terminamos hoy.

A tenor de is a fixed, fairly formal expression meaning something like according to, in light of, or based on.

In this sentence, it introduces the basis for the statement:

A tenor de este horario autorizado, terminamos hoy.
= According to this approved schedule, we finish today.

It is not something most learners hear all the time in casual conversation; it sounds more official or administrative.

No. Even though it is the same spelling, it is not about a singing voice here.

In a tenor de, tenor is part of a fixed expression with an older, formal meaning related to the content, sense, or terms of something.

So in this sentence, you should learn a tenor de as one whole expression, not by trying to connect tenor to the musical meaning.

It is understood, but it sounds formal, bureaucratic, or written.

In everyday spoken Spanish in Spain, people would more often say things like:

• Según este horario, terminamos hoy.
• Con este horario, terminamos hoy.
• De acuerdo con este horario, terminamos hoy.

So yes, it is correct, but it is not the most casual option.

Because horario is a masculine noun in Spanish.

So the words agreeing with it must also be masculine singular:

• este = masculine singular this
• autorizado = masculine singular authorized/approved

That is why the phrase is:

este horario autorizado

and not esta horario autorizada.

Autorizado describes horario.

So the phrase means:

• horario = schedule/timetable
• autorizado = authorized/approved

Together: authorized schedule or approved timetable

Grammatically, autorizado is a past participle used like an adjective. It agrees with horario in gender and number.

In Spanish, demonstratives like este, ese, and aquel normally replace the article rather than combine with it.

So you say:

• este horario = this schedule
• not este el horario

This works like English: you say this schedule, not this the schedule.

Terminamos is the present indicative of terminar for nosotros: we finish / we are finishing.

In Spanish, the present tense is often used to talk about a planned or scheduled future event, especially when the time is clear from context:

• Mañana salimos temprano.
• El tren llega a las ocho.
• Terminamos hoy.

So here, terminamos hoy can naturally mean we finish today or we’re finishing today, based on the approved schedule.

Normally, no.

Terminamos is present tense, not a past tense. It usually means:

• we finish today
• we are finishing today

If you wanted we finished today, Spanish would normally use a past tense, such as:

• Hemos terminado hoy.
• Terminamos hoy, in some narrative contexts, could be interpreted differently, but that would not be the normal reading here.

In this sentence, the natural meaning is present/future-looking, based on the schedule.

The subject is nosotros = we, but Spanish often leaves subject pronouns out because the verb ending already shows who the subject is.

• termino = I finish
• terminas = you finish
• termina = he/she/it finishes
• terminamos = we finish

So terminamos already clearly means we finish, and adding nosotros is usually unnecessary unless you want emphasis or contrast.

The comma separates the introductory phrase from the main clause.

• Introductory phrase: A tenor de este horario autorizado
• Main clause: terminamos hoy

This comma is natural because the sentence begins with a relatively long formal expression. It helps readability.

You may sometimes see short introductory phrases without commas, but here the comma is stylistically very normal.

Very likely, yes. A more natural everyday version might be:

• Según este horario, terminamos hoy.
• Con este horario, terminamos hoy.
• Según el horario autorizado, terminamos hoy.

The original sentence is correct, but a tenor de sounds more formal and official than what many people would say in ordinary conversation.

Este means this, while ese means that.

Using este horario autorizado suggests the speaker is referring to the schedule as something close, present, or directly relevant in the situation, for example a schedule being looked at right now.

• este horario = this schedule
• ese horario = that schedule

In practice, Spanish demonstratives depend on how the speaker mentally or physically places the thing being referred to.

Horario usually means schedule, timetable, or hours.

In this sentence, it means something like a work or activity schedule. It refers to the planned timetable that has been approved.

Depending on context, English might translate it as:

• schedule
• timetable
• approved hours

So horario is a broad word, and the best translation depends on the situation.
