Old French[edit]


From Latin adiutāre, present active infinitive of adiūtō (help, assist).




  1. (transitive) to help


This verb conjugates as a first-group verb ending in -ier, with a palatal stem. These verbs are conjugated mostly like verbs in -er, but there is an extra i before the e of some endings. This is an irregular verb with a stressed stem containing an extra syllable: aiu-. Early versions had the stressed stem aiuḍ-, this -ḍ- is the reason the second person singular subjunctive ends in -z. The alternative form of the third person singular subjunctive present aïst and other stems in aï- is rather a reflex from shortened Vulgar Latin *adiŭtet. It is cognate with Spanish ayudar and Italian aiutare. Old French conjugation varies significantly by date and by region. The following conjugation should be treated as a guide.
