Condicional simple: verbos regulares

The condicional simple is Spanish's would-tense — the morphological form used to express what would happen under hypothetical conditions, to soften requests, to report a future from a past vantage point, and to make polite suggestions. The form is mechanically as simple as a Spanish tense gets: take the whole infinitive, attach the same six endings, and you are done. Every regular verb uses the same set of endings regardless of whether it ends in -ar, -er, or -ir. Every form carries a written accent on the -í-. And the same irregular stems that warp the simple future also warp the conditional in exactly the same way.

This page covers the regular formation: the six endings, the accent rules, the peninsular vosotros form, and the relationship between the conditional and the simple future that makes the whole system click.

The mechanic: whole infinitive + the same six endings

Like the simple future, the conditional is built on the whole infinitive, not on a stem. You do not strip -ar, -er, or -ir — you keep the entire infinitive and add the ending. This is what unifies the conditional system across the three conjugation classes.

Three facts stand out:

1. The same set of endings applies to all three conjugation classes — -ía, -ías, -ía, -íamos, -íais, -ían. There is no -ar / -er / -ir split, exactly like the simple future.
2. Every form carries a written accent on the -í-. There is no unaccented form anywhere in this tense — nosotros (hablaríamos) is also accented, unlike the simple future where nosotros is the one exception.
3. The first-person singular and the third-person singular are identical (hablaría = I would speak = he/she would speak). Context tells them apart.

Why the accents are not optional

The conditional endings start with a stressed -í-: habl-a-RÍ-a, habl-a-RÍ-as, habl-a-RÍ-a-mos. Spanish stress would normally put the accent on the penultimate syllable — but for words like hablaria (no accent), the stress would land on the -ria and the meaning collapses. The written accent on -í- is what locks the stress onto that vowel and keeps the conditional distinct from any other form.

Critically, the accent is necessary because of a Spanish spelling rule about diphthongs. The sequence ía is naturally a single syllable (a falling diphthong, ia), but the accent on í breaks it into two syllables — making ha-bla-rí-a a four-syllable word, with stress on the third syllable. Without the accent, the word would be ha-bla-ria (three syllables, stress on the second), which is not how the tense sounds at all.

The takeaway: every conditional form requires the accent. There is no form in the tense without one.

The peninsular vosotros: -íais with the accent on -í-

In Spain, the second-person plural conditional is -íais — and the accent is on the í, not on the a. This is the peninsular form you will hear in conversation with two or more friends.

(Vendríais uses the irregular stem vendr- + the ending -íais. The regular pattern of the ending is the same as for hablar: hablaríais.)

A common error is to write hablariais without the accent. This is a misspelling, not a casual variant — the form requires the accent on the í to mark the stress and to break the diphthong.

The conditional / future twinship

The conditional and the simple future are structural twins: they share the same base (the whole infinitive), the same irregular stems, and a closely related set of endings.

If you already know the simple future, the conditional is half-learned. The irregular stems — tendr-, pondr-, saldr-, vendr-, valdr-, podr-, sabr-, cabr-, querr-, habr-, har-, dir- — are identical in the two tenses. You will see tendría paralleling tendré, haría paralleling haré, diría paralleling diré. (See the page on irregular conditional stems for the full inventory and the spelling trap with querría.)

What the conditional means

Like the simple future, the conditional has multiple uses — but unlike the future, the conditional almost never refers to actual future events. Its core meanings cluster around hypothesis, politeness, indirect statements, and conjecture about the past.

Use 1: hypothetical situations

The conditional is the tense of what would happen if... statements. The full pattern is si + imperfect subjunctive + conditional for present-counterfactual conditions.

This is the classic "type 2 conditional" — see the dedicated page on hypothetical si-clauses for more.

Use 2: polite requests and softening

The conditional softens a request more than the imperfect (quería) and is felt as polished and considerate.

In Spain, both quería (imperfect, colloquial) and querría (conditional, polished) are heard for "I would like". The conditional is the more formal of the two.

Use 3: future of the past (reported speech)

When a past reporting verb introduces what someone said about the future, the future shifts to a conditional — exactly parallel to English will → would.

This is one of the cleanest English-Spanish parallels in the language. Dijo que vendría = he said he would come. (See the page on reported speech for the full tense-shift table.)

Use 4: conjecture about the past

Just as the simple future expresses guesses about the present (serán las cinco = it must be around five), the conditional expresses guesses about the past.

This conjectural conditional is high-frequency in peninsular storytelling — you will hear it constantly when someone is recalling something inexactly and estimating.

A summary table: regular conditional for the three model verbs

For quick reference, here are all six forms of all three model verbs side by side.

Pick one model verb and learn it well — the endings are identical for the other two. The standard choice is hablar because -ar verbs are the largest class.

Common Mistakes

The nosotros conditional ends in -íamos with an obligatory accent on the í. Hablariamos without the accent is a misspelling — and the most common conditional spelling error among learners. Without the accent, the syllable structure of the word changes (ha-bla-ria-mos instead of ha-bla-rí-a-mos).

English speakers sometimes use the imperfect for "I would" because English would can mean both hypothetical (I would talk) and habitual past (I used to talk). In Spanish, these are completely different tenses. Hablaba = habitual past; hablaría = hypothetical. Pick the right one based on whether you mean would do (hypothetical) or used to do (habitual).

In hypothetical si-clauses, the si clause takes the imperfect subjunctive (tuviera or tuviese), and the main clause takes the conditional (viajaría). The conditional never sits inside a si clause in this construction.

The peninsular vosotros conditional ends in -íais with the accent on the í. Without the accent, the diphthong rules collapse the form. This is structurally the same issue as the nosotros form (-íamos) — the accent on -í- is what makes the tense work orthographically.

When the reporting verb is in the past (dijo, me dijo, prometió, avisó), the future tense in the original statement shifts to the conditional. Dijo que vendrá breaks the tense agreement that Spanish maintains so strictly in reported speech.

This is the mirror image of the first mistake: English would in a habitual sense (we would speak Spanish every day) maps onto the Spanish imperfect, not the conditional. Match the meaning, not the English word.

Key takeaways

• The conditional is built by adding -ía, -ías, -ía, -íamos, -íais, -ían to the whole infinitive.
• The same endings apply to every regular verb regardless of conjugation class.
• Every form carries an accent on -í- — including nosotros (hablaríamos) and vosotros (hablaríais).
• The conditional shares all 12 irregular stems with the simple future (tendría, pondría, sabría, haría, diría…) — see the dedicated page.
• Core uses: hypothetical situations, polite requests, future of the past in reported speech, and conjecture about the past.
• English would sometimes means used to — for that meaning, use the imperfect (hablábamos), not the conditional.
