Linking ideas like a native

When you tell a story or give instructions, Spanish marks each step with a small time word. The most useful set:

• primero — first

• luego / después — then, afterwards (interchangeable in most contexts)

• entonces — then, at that moment (or "so", in conversation)

• al final / finalmente — in the end, finally

The trap is después. On its own it means "afterwards": Después, fuimos al cine. Before a noun or an infinitive it needs de: después de comer, después de la clase. English "after lunch" is never después la comida.

Al final is the everyday "in the end", often with a hint of "after all that": Al final no vino. Finalmente is a little more neutral or formal and works well as the last item in a list of steps. Don't use en fin for "finally": it means "anyway" or "well".

In Mexico and elsewhere luego can also mean "later" or even "right away" depending on the region, but in a sequence of steps it means "then" everywhere.

Four connectors do most of the work of joining two ideas:

• porque — because: No fui porque estaba cansado.

• pero — but: Es caro, pero es muy bueno.

• así que — so (as a result): Llovía, así que nos quedamos en casa.

• por eso — that's why, for that reason: Perdí el bus. Por eso llegué tarde.

Watch the spelling: porque (one word, no accent) answers; ¿por qué? (two words, accent) asks. And "because of" before a noun is not porque: say por la lluvia or a causa de la lluvia.

English "so" has two jobs. "So tired" is intensity and becomes tan cansado. "It was late, so we left" is a result and becomes así que or por eso. Learners often write tan for the second one; it never works there.

Por eso points back to a reason you already gave, so it often starts a new sentence. Así que links straight on, after a comma. Both are correct for a result; entonces is also common in speech.

Aunque means "although" or "even though". It introduces a fact that you'd expect to stop the main action, but doesn't: Aunque estaba cansada, terminó el informe. It can go first or second, like in English.

When the fact is real and known, aunque takes the indicative. When you mean "even if" — something hypothetical or not yet known — it takes the subjunctive: Aunque llueva, iremos ("even if it rains"). For "although" about something that happened or is true, stay in the indicative.

Two neighbours, not to be confused:

• sin embargo — "however": it starts the second idea, usually after a full stop or semicolon: Era tarde. Sin embargo, seguimos trabajando.

• mientras que — "whereas": it sets two things side by side: Yo cocino, mientras que él lava los platos. Plain mientras means "while" in time.

The English trap is "though" at the end of a sentence: "It was cheap, though." Spanish has no tag like that; say Pero era barato or start with aunque. And "even though" is just aunque, never incluso aunque.

A relative clause describes a noun you've just mentioned: "the woman who lives upstairs", "the cake I made". In Spanish the workhorse is que, and it covers both people and things: la mujer que vive arriba, el pastel que hice.

The big English-speaker trap: English happily drops the relative word. "The cake I made", "the film we saw". Spanish never does. You must write el pastel que hice, la película que vimos. If you can insert "that" or "which" in English, Spanish needs que.

Second trap: don't translate "who" as quien by reflex. In a plain restrictive clause la mujer quien vive arriba is wrong; it's la mujer que vive arriba. Quien appears after a preposition (la amiga con quien viajo) or between commas (mi jefe, quien es muy simpático, ...).

When "what" means "the thing that", Spanish uses lo que: No entiendo lo que dices. And keep the accent off: relative que has none; only the question word qué does.

English lets a preposition dangle at the end of a relative clause: "the colleague I work with", "the film I told you about". Spanish never strands a preposition. It moves to the front, followed by an article and que:

• el compañero con el que trabajo

• la película de la que te hablé

• la empresa para la que trabaja

The article agrees with the noun it refers back to: el que, la que, los que, las que. For people you can also use quien / quienes without an article: el compañero con quien trabajo. In formal writing el cual / la cual does the same job: la razón por la cual dimitió.

To build these, find the verb in the clause and ask which preposition it needs in Spanish, not in English. "Talk about" is hablar de, so del que te hablé. "Lend to" is prestar a, so al que le presté. Remember de + el = del and a + el = al.

Leaving out the preposition (el compañero que trabajo) is a classic error, and so is copying the English one. Also note that lo que refers to a whole idea, not a noun: lo que te conté.

Porque gives a reason as new information, usually after the main clause. When the reason is already known or obvious — you're presenting it as a given — Spanish prefers ya que, puesto que or dado que: Ya que estás aquí, ayúdame con esto. They can go first or second. Puesto que and dado que sound a bit more formal.

Como also works for a known reason, but only at the start of the sentence: Como no contestabas, me fui.

The English trap is "since". Causal "since" is ya que; time "since" is desde or desde que: Vivo aquí desde 2019. If "since" could be replaced by "because" or "seeing as", it's causal.

This family has siblings worth knowing:

• debido a / a causa de + noun — "due to", "because of": debido al mal tiempo

• por lo tanto / por consiguiente — "therefore", formal conclusion

• así que — everyday "so"

• a pesar de — "despite": a pesar de la lluvia

Note that after debido a comes a noun; before a full clause it's debido a que.

Spoken Spanish is held together by small markers that steer the listener. De hecho — "in fact" — takes what you just said and pushes it further with a confirming detail: No me molesta; de hecho, me encanta. The second idea must go in the same direction as the first, only stronger.

The trap is English "actually". When "actually" corrects a wrong impression ("Actually, I'm from Chile, not Peru"), Spanish says en realidad. When it upgrades a claim, it's de hecho. And actualmente means "currently", never "actually".

Its conversational cousins:

• por cierto — "by the way", for an aside: Por cierto, ¿llamaste a tu madre?

• o sea — "I mean", "in other words", to reformulate

• la verdad es que — "honestly", "the truth is", for a candid admission

• total, que — "long story short", to jump to the outcome

• en cambio — "on the other hand", to contrast two cases

• ahora bien — "that said", to add a serious caveat

Fíjate que ("get this") is especially frequent in Mexico and Central America; the rest are used everywhere.

Formal and written Spanish has a heavier set of connectors. The most important is no obstante, "nevertheless" or "nonetheless". It concedes the weight of what came before and then holds its ground: El proyecto es ambicioso. No obstante, carece de financiación. It usually opens the second sentence or follows a semicolon, and it can sit mid-clause between commas: La empresa, no obstante, seguirá operando.

Sin embargo is its near-synonym and is correct in the same slot, but no obstante signals a more deliberate, written register: reports, essays, legal and journalistic prose. In casual speech it sounds stiff; there, pero or aun así is natural.

The same register has:

• por ende — "hence", "therefore": La demanda cayó y, por ende, los precios.

• a sabiendas de que — "knowing full well that": Firmó a sabiendas de que era un error.

• habida cuenta de (que) — "in view of", "given": habida cuenta de las circunstancias

The English-speaker trap is register mismatch: dropping no obstante into a chat with a friend, or writing pero at the start of a formal paragraph where a full connector is expected.
