- Principal parts
In
language learning, the principal parts of averb are those forms that a student must memorize in order to be able to conjugate the verb through all its forms.By language
English
In English, the verb "love" derives all its forms systematically ("love, loves, loved, loving"), and since these can all be deduced from the basic form (the citation, dictionary, or lexicographic form, which in English is the bare
infinitive ), no other principal parts have to be learned. Withirregular verbs like the verb "sing", on the other hand, the forms "sang" and "sung" cannot be deduced, so the learner of English must memorise three principal parts, "sing – sang – sung". From these, all other forms (like "sings" or "singing") can be deduced. "(See alsoEnglish verbs ,English irregular verbs ,English as an additional language .)"Latin
In
Latin , most verbs have four principal parts. The verb for "to carry" has the parts "portō – portāre – portāvī – portātus". "Portō" is the first person singular form of the present ("I carry"), but the infinitive "portāre" ("to carry") is also needed to deduce all the forms of the present stem. The perfect stem "portāvī" ("I carried") and the supine stem "portātus" (required for the perfect passive participle). Another example, the verb "to praise" has the parts "laudā - laudāre - laudāvī - laudātus". "Laudā" and "laudāre", the present active indicative first person singular and the present active infinitive are needed to deduce the present stem. "Laudāvī" is needed for the perfect stem, while "laudātus" is required for the perfect passive participle.panish
In Spanish, verbs are traditionally held to have only one principal part, the infinitive, by which one can classify the verb into one of three conjugation paradigms (according to the ending of the infinitive, which may be "-ar", "-er" or "-ir"). However, some scholars believe that the conjugation could be regularized by adding another principal part to vowel-alternating verbs, which shows the alternation. For example, "herir" "to hurt" is usually considered irregular because its conjugation contains forms like "hiero" "I hurt", "hieres" "you hurt", where the vowel in the root changes into a diphthong. However, by including the first person singular, present tense, indicative mood form ("hiero") as a principal part, and noting that the
diphthong appears only when that syllable is stressed, the conjugation of "herir" becomes completely predictable. "(See alsoSpanish verbs ,Spanish conjugation .)"cottish Gaelic
In
Scottish Gaelic there are two principal parts for the regular verb: "pog – pogadh". All finite forms can be deduced from the imperative "pog" ('kiss!'), all non-finite forms from the verbal noun "pogadh" ('kissing'). The ten irregular verbs can, with only two or three small aberrations (unexpected lenition), be deduced from four principal parts.ee also
