There are two kinds of changes that can affect stem vowels of some Spanish verbs: diphthongization and vowel raising. Both changes affect -e-or -o-in the last (or only) syllable of a verb stem. Diphthongization changes -e-to -ie-, and -o-to -ue-. Vowel raising changes the mid vowels-e-and -o-to the corresponding high vowels: -i-and -u-respectively.
To form the gerund of an -ar verb, replace the -ar of the infinitive with -ando; e.g. jugar, hablar, caminar → jugando, hablando, caminando. For -er or -ir verbs, replace the -er or -ir ending with -iendo; e.g. comer, escribir, dormir → comiendo, escribiendo, durmiendo (note that dormir undergoes the stem vowel change that is typical of -ir ...
To conjugate something that is positive in the imperative mood for the tú form (which is used most often), conjugate for the tú form and drop the s. To conjugate something that is negative in the imperative mood for the tú form (which also is used most often), conjugate in the yo form, drop the o, add the opposite tú ending (if it is an -ar ...
Similarly, the participle agrees with the subject when it is used with ser to form the "true" passive voice (e.g. La carta fue escrita ayer 'The letter was written [got written] yesterday.'), and also when it is used with estar to form a "passive of result", or stative passive (as in La carta ya está escrita 'The letter is already written.').
The preterite and past participle forms of irregular verbs follow certain patterns. These include ending in -t (e.g. build, bend, send), stem changes (whether it is a vowel, such as in sit, win or hold, or a consonant, such as in teach and seek, that changes), or adding the [n] suffix to the past participle form (e.g. drive, show, rise ...
The preterite or preterit (/ ˈ p r ɛ t ər ɪ t / PRET-ər-it; abbreviated PRET or PRT) is a grammatical tense or verb form serving to denote events that took place or were completed in the past; in some languages, such as Spanish, French, and English, it is equivalent to the simple past tense.
The weak conjugation is also the origin of the regular verbs ending in -ed; however various historical sound changes (and sometimes spelling changes) have led to certain types of irregularity in some verbs. The main processes are as follows (some verbs have been subject to more than one of these).
The future indicative tense does not derive from the Latin form (which tended to be confounded with the preterite due to sound changes in Vulgar Latin), but rather from an infinitive + habeō periphrasis, later reanalysed as a simple tense. Formally identical to the future perfect indicative, the two paradigms merged in Vulgar Latin.
