Gerund: desmintiendo · Past participle: desmentido
The gerund is desmintiendo, which you use with estar to say what is happening right now: “Estoy desmintiendo” means the action of desmentir is in progress at this very moment. The past participle is desmentido, which you use with haber in the perfect tenses: “he desmentido” is the present perfect, used for a completed action. Keep both forms in mind as you read the examples below, because the present is only one part of how desmentir is used.
How the present of desmentir is formed
desmentir is a -ir verb. Take the stem desment and add the present endings for -ir verbs: -o, -es, -e, -imos, -ís, -en, giving desmiento, desmientes, desmiente, desmentimos, desmentís and desmienten. But desmentir is not fully regular here: it changes its stem (e → ie), so the stem in the table is not the infinitive stem in several persons. Learn the six forms as a set rather than building them from the infinitive each time.
The present of desmentir rewards careful reading of the table. Two details deserve attention. First, the yo form desmiento is the form you will use most when you talk about yourself, so say it out loud until it comes without thinking. Second, the nosotros form desmentimos and the ellos form desmienten are the ones learners confuse most often, because they are the forms used for groups. Practise the six forms in order — yo, tú, él, nosotros, vosotros, ellos — and the pattern will settle.
When to use the present of desmentir
The present is not a single-purpose tense. Below are the five situations where you will use desmentir in the present most often. Each one comes with a real example, so read the rule, then say the example out loud.
1. A habit or routine
desmentir in the present describes something done regularly. When talking about the rumour is part of your routine, the present is the right tense. Example: “Yo desmiento el rumor cada día.” — “I deny the rumour.”
2. A fact or general truth
General truths about the rumour also take the present. The tense states how things are, not when they happened. Example: “Él desmiente el rumor siempre.” — “He denies the rumour.”
3. Something happening right now
Use the present for what is happening at this moment. It is the simplest way to describe an action in progress when you do not need the gerund. Example: “Nosotros desmentimos el rumor ahora mismo.” — “We deny the rumour.”
4. A scheduled near-future event
Spanish often uses the present for plans that are already fixed, especially with a time expression. It sounds more certain than the future tense. Example: “Ellos desmienten el rumor mañana.” — “They deny the rumour.”
5. Instructions and explanations
When you explain how something works — how to talk about the rumour — the present is the natural tense. Recipes, rules and directions all live in the present. Example: “Tú desmientes el rumor normalmente.” — “you deny the rumour.”
Present Tense vs Preterite: how to choose
The closest tense to the present is the preterite, and choosing between them is one of the hardest decisions in Spanish. The rule is simple: the present reports what happens regularly or is happening now, while the preterite reports one finished action. The three pairs below use the same verb, so the only thing that changes is the tense. Time words help: cada día and siempre point to the present, while ayer points to the preterite.
Present Tense: “Yo desmiento el rumor cada día.” — “I deny the rumour.”
Preterite: “Yo desmentí el rumor ayer.” — “I denyed the rumour.”
The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: a habit or a present fact versus one finished event. That difference is the whole decision.
Present Tense: “Él desmiente el rumor siempre.” — “He denies the rumour.”
Preterite: “Él desmintió el rumor ayer.” — “He denyed the rumour.”
The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: a habit or a present fact versus one finished event. That difference is the whole decision.
Present Tense: “Nosotros desmentimos el rumor todos los días.” — “We deny the rumour.”
Preterite: “Nosotros desmentimos el rumor ayer.” — “We denyed the rumour.”
The two sentences use the same verb and the same situation, but the tense changes what the sentence claims: a habit or a present fact versus one finished event. That difference is the whole decision.

Read these eight sentences out loud. They cover all six persons, so by the end you will have seen every form in the table used in a real sentence.

Common mistakes
Using the unchanged stem
Learners often write desmento for the yo form, keeping the infinitive stem unchanged. The correct form is desmiento. Because desmentir changes its stem vowel, the change appears in the stressed syllables of the present: say the correct form out loud a few times — yo desmiento el rumor — until the changed stem feels natural.
Confusing desmentir with descubrir
desmentir and descubrir look similar, and learners mix them up. They are different verbs with different meanings, so check which one the sentence needs before you conjugate. If you can substitute the English meaning of desmentir — deny — the sentence needs desmentir; if it needs the meaning of descubrir, use that verb instead.
Using the indicative after "espero que"
After espero que (I hope that), Spanish needs the subjunctive: Espero que yo desmienta el rumor. Using the indicative — Espero que yo desmiento — is one of the most frequent learner errors with desmentir. Whenever the main clause expresses a wish, doubt or emotion, switch to the subjunctive.
Using the unchanged stem
Learners often write desmento for the yo form, keeping the infinitive stem unchanged. The correct form is desmiento. Because desmentir changes its stem vowel, the change appears in the stressed syllables of the present: say the correct form out loud a few times — yo desmiento el rumor — until the changed stem feels natural.
Using the wrong tense for desmentir
The most general mistake is choosing the wrong tense altogether: using the present where Spanish needs the preterite, or the other way round. Check the time words first — ayer and la semana pasada point to the past, cada día and siempre point to the present — and then check whether the action is finished or ongoing. If you can answer those two questions, the tense usually chooses itself.
