Spanish irregular verb conjugation is a simple way of remembering

Verb conjugation in Spanish is a headache for many middle-level learners. But you know what? In fact, irregular verbs also have their own rules (except for complete irregularities).
Although there are many kinds of tenses in Spanish, there are actually only three types of irregular roots! Take a look at the simplest way to memorize Spanish conjugations below!

Regardless of the rules or not, remember the third person singular first

For example, the declarative present tense third person singular +S→ second person singular /+N→ third person plural
trabaja→ trabajas/trabajan, sigue→ sigues/siguen

Among irregular conjugation verbs, the declarative first and second person plurals are still the majority of the rules, while the virtual tense is completely irregular.

Temporal sharing irregular roots:

• Declarative present-time first-person singular = imperative third-person singular = virtual tense
  conozco → conozca → conozca
• Declarative simple past tense third person singular = virtual past unfinished
  sintió → sintiera
• Declarative future tense = conditional
  pondré → pondría

Vowel change (penultimate syllable variation) (based on declarative form)

• e + ir →ie (present tense), →i (simple past tense third person)
  sentir → siento → sintió / sintieron,
  preferir→ prefiero → prefirió /prefieron
• e + ir →i (present tense), →i (simple past tense third person)
  pedir → pido →pidió / pidieron
• e + er/ar →ie (present tense)
  pensar →pienso, entender → entiendo
• o + ir →ue (present tense), →u (simple past tense third person)
  dormir →d uermo →durmió / durmieron
• o + er/ar →ue (present tense)
  contar → cuenta, llover → llueve

Change the vowel (leave no word: the letter will be changed, but the pronunciation is saved)

• car + e → que (all conjugations of the end of the e word)
  indicar → indiqué →indique
• zar + e → ce (all conjugations of the e-ending)
  comenzar → comencé →comience
• cer/cir + o/a → zco /zca (declarative/virtual present tense)
  conocer → conozco / conozca, introducir → introduzco / introduzca
• UCIR → -j- (simple past tense)
  introducir → introdujo
• gar + e→ gue (all conjugations of the e-ending)
  ahogar → ahogué → ahogue
• ger/gir + a/o → ja/ jo (all conjugations of a/o endings)
  coger → cojo → coja, elegir → elijo → elija
• guir + a/o → ga/ go (all a/o end-of-line conjugations)
  seguir → sigo → siga
• guar + e→ güe (all conjugations of the end of
  the e word) averiguar → averigüe
• uir + a/e/o→ ya / ye / yo (all a/e/o end-of-line conjugations)
  incuir → incluyo / incluye / incluya
• eer + i- → y (contains the conjugation of the i- end)
