Conjugation Calculator
Type a verb, pick a language and a tense, and get the full six-person conjugation table. This tool conjugates English, Spanish, and French verbs in the present, past, and future, with true forms for the common irregular verbs it knows and an honest label on everything it builds from the regular pattern. It is pre-filled with hablar in the Spanish past, the classic first conjugation every Spanish learner meets.
Identity note, stated plainly: this is the grammar word, conjugation, as in conjugating a verb. It is not the mathematics term for complex conjugates, and no complex numbers appear anywhere in the tool.
Regular verbs follow standard patterns; listed irregulars use their true forms. Stem-changing and spelling-change verbs are conjugated with the regular pattern and labeled as such.
Quick Answer
Key takeaways
- Three languages, three tenses: English, Spanish, and French across present, past, and future, six persons each.
- Spanish past here is the preterite (completed actions). French past is the passe compose, built from avoir plus the past participle, which is how spoken French reports completed actions.
- Known irregulars get their true forms: be, have, go, do, see in English; ser, estar, tener, ir in Spanish; etre, avoir, aller, faire in French, plus 68 common English irregular pasts.
- Anything outside the stored irregulars is built with the regular pattern and labeled as such. Stem-changing verbs are the known limit: check those against a dictionary conjugator.
How to use the conjugation calculator
Type the infinitive, the dictionary form of the verb: hablar or comer in Spanish, parler or finir in French, walk or write in English. In English, typing the word to first is fine; the tool strips it. Then pick the language and the tense and press Conjugate.
Read the label under the verb before you trust the table. Irregular means the tool used stored, true forms for that verb. Regular (standard pattern) means it applied the standard endings for the verb's group, which is correct for genuinely regular verbs and an approximation for stem-changing or spelling-change verbs, as the limits section explains. The Purdue OWL's introduction to verb tenses is a good companion read for the English side, where only two tenses are carried by the verb form itself and the rest lean on auxiliaries like will and have.
How the three languages conjugate differently
English barely conjugates at all. In the present tense only the third person singular changes (walk becomes walks); the past is one form for every person (walked), and the future is will plus the bare verb for everyone. Spanish and French conjugate for every person, so the ending itself carries who is acting, and the pronoun can often be dropped.
| Feature | English | Spanish | French |
|---|---|---|---|
| Present tense forms | 2 (walk, walks) | 6 per verb group | 6 per verb group |
| Past tense in this tool | Simple past, 1 form | Preterite, 6 forms | Passe compose: avoir + participle |
| Future formation | will + verb | Endings on the infinitive | Endings on the infinitive (drop final e of -re verbs) |
| Verb groups | Regular vs irregular pasts | -ar, -er, -ir | -er, -ir, -re |
| Stored irregulars here | 5 full verbs + 68 pasts | ser, estar, tener, ir (present) | etre, avoir, aller, faire (present) |
The regular patterns are systematic enough to state in one breath each. Spanish present: drop -ar, -er, or -ir and add the group endings (hablar gives hablo, hablas, habla, hablamos, habláis, hablan). Spanish and French futures both grow directly out of the infinitive: hablaré, hablarás, hablará in Spanish; parlerai, parleras, parlera in French. French past works differently in this tool, and more usefully for learners: it builds the passe compose with the present tense of avoir, which the University of Texas Tex's French Grammar treats the same way, reserving the simple past mainly for written narrative.
Worked examples in all three languages
The calculator is pre-filled with the first example. All three tables below are what the tool returns, checked against its code.
| Person | hablar, Spanish past | parler, French past | walk, English past |
|---|---|---|---|
| 1st singular | yo hablé | je: ai parlé | I walked |
| 2nd singular | tú hablaste | tu: as parlé | you walked |
| 3rd singular | él/ella habló | il/elle: a parlé | he/she/it walked |
| 1st plural | nosotros hablamos | nous: avons parlé | we walked |
| 2nd plural | vosotros hablasteis | vous: avez parlé | you (plural) walked |
| 3rd plural | ellos/ellas hablaron | ils/elles: ont parlé | they walked |
Two details worth noticing. In spoken French the first row contracts to j'ai parlé; the tool displays the auxiliary and participle in full so the construction stays visible to learners, which is the right trade for a teaching tool. And the Spanish nosotros preterite of an -ar verb, hablamos, is spelled identically to its present tense; context, not form, tells you which tense a speaker means. That collision is real Spanish, not a tool error.
The irregular verbs this tool actually knows
Claims about irregular coverage are where conjugators usually get vague, so here is the exact inventory from the code. English: be, have, go, do, and see carry full stored present and past tables, and 68 further verbs carry stored irregular pasts, including run to ran, eat to ate, write to wrote, teach to taught, and swim to swam. Spanish: ser, estar, tener, and ir carry stored present-tense forms (soy, eres, es; estoy, estás, está; tengo, tienes, tiene; voy, vas, va). French: etre, avoir, aller, and faire carry stored present-tense forms (suis, es, est; ai, as, a; vais, vas, va; fais, fais, fait).
Everything else is conjugated with the regular pattern for its ending group and labeled Regular (standard pattern) on the result. That labeling is the feature to value: a tool that quietly applies regular endings to an irregular verb teaches you a wrong form with total confidence. This one tells you which kind of answer you are looking at.
What competing calculators miss
The full conjugators, WordReference and Reverso and the Gymglish family, are excellent and deep: every tense and mood, one language at a time, inside large dictionary sites. The previous version of this page, by contrast, handled only the present tense for Spanish and French and echoed the infinitive back for verbs it did not recognize. This version sits deliberately between those poles.
Miss 1: one language per tool. Learners comparing how three languages handle the same idea have to open three different conjugators. Here English, Spanish, and French sit behind one input, which makes side-by-side comparison the default instead of a research project.
Miss 2: silent invention. Lightweight conjugators that meet an unknown verb often return something anyway, unlabeled. This tool either knows the form, builds it from the stated regular pattern and labels it, or, for a verb ending it cannot parse, refuses with an error asking for an infinitive in -ar, -er, -ir, or -re.
Miss 3: no past or future in quick tools. Present-tense-only tools strand learners at the first narrative sentence. The preterite, the passe compose, and both futures are the tenses beginners actually need next, and all are here.
The honest boundary stands: for subjunctive, conditional, imperfect, or a stem-changing verb's exact forms, a full dictionary conjugator remains the authority, and this page says so rather than pretending otherwise.
Frequently Asked Questions
Drop the infinitive ending and add the endings for its group. For -ar verbs like hablar: hablo, hablas, habla, hablamos, habláis, hablan. For -er verbs the yo form also ends in -o but the rest differ (como, comes, come, comemos, coméis, comen), and -ir verbs match -er except in nosotros and vosotros (vivo, vives, vive, vivimos, vivís, viven).
The past tense for completed actions: things that happened and finished. Regular -ar endings are é, aste, ó, amos, asteis, aron, so hablar becomes hablé, hablaste, habló, hablamos, hablasteis, hablaron. It contrasts with the imperfect, which covers ongoing or habitual past actions and is not one of the tenses this tool covers.
Take the present tense of avoir and add the past participle: j'ai parlé, tu as parlé, il a parlé, nous avons parlé, vous avez parlé, ils ont parlé. The participle of a regular -er verb ends in é, of -ir in i, of -re in u. Some common verbs use etre as the auxiliary instead of avoir in real French; this tool builds the regular pattern with avoir and labels it as such.
Both languages add endings directly to the infinitive. Spanish: é, ás, á, emos, éis, án, giving hablaré, hablarás, hablará. French: ai, as, a, ons, ez, ont, giving parlerai, parleras, parlera; -re verbs drop the final e first, so prendre builds on prendr-. English simply uses will plus the bare verb for every person.
In Spanish: ser (soy, eres, es), estar (estoy, estás, está), tener (tengo, tienes, tiene), and ir (voy, vas, va). In French: etre (suis, es, est), avoir (ai, as, a), aller (vais, vas, va), and faire (fais, fais, fait). This tool stores the true present-tense forms for all eight and labels them Irregular when you conjugate them.
English shed most of its verb endings over the centuries. What survives is the third person singular -s in the present (he walks), a set of irregular pasts inherited from older patterns (go to went, eat to ate), and auxiliary verbs like will, have, and do doing the work that endings do in Spanish and French.
No. It covers the present, past, and future in the indicative mood for English, Spanish, and French. For subjunctive, conditional, imperfect, or the exact forms of a stem-changing verb, use a full dictionary conjugator. The tool labels every regular-pattern result so you always know whether you are looking at a stored form or a constructed one.
No. Conjugation here is the grammar term: changing a verb's form by person, tense, and number. The math term, complex conjugate, means flipping the sign of the imaginary part of a complex number, as in 3 + 2i becoming 3 – 2i. Despite the shared name and this page's title, the tool does grammar only, and it says so up front rather than letting the ambiguity stand.
