ajudar (first-person singular present ajudo, first-person singular preterite ajudei, past participle ajudado)[1] Houaiss records aiudar and aaiudar beside ajudar in the 13th century, and the learned variant adjudar in the 15th.[2][3]
Etymology
It is inherited from Latin adiūtō (“to help, assist”), written Old Galician-Portuguese ajudar in the oldest texts.[2][4][3][5][1] The Latin verb is the frequentative of adiuvō (“to come to the aid of, help”).[2][6] Machado notes that it was avoided in classical prose but lived on in the spoken language as an expressive, intensive verb;[3] Petronius puts it in the mouth of Trimalchio.[3]
The same Latin word is Galician axudar, Spanish ayudar, Catalan ajudar, Occitan ajudar, French aider, Italian aiutare and Romanian ajuta.[7][1] García de Diego adds audar, an Old Leonese form of 1197.[8]
That verb is formed ad- and iuvō (“to help”).[9][10] De Vaan reconstructs a Proto-Italic stem *ijow- and a Proto-Indo-European present *h₁i-h₁euH- (“to help”), with cognates in Old Irish and Sanskrit;[10][1] Wiktionary calls the further origin uncertain.[10][1]
Earliest recorded meaning
The verb appears in Romance form inside two Latin charters of 1075 from the monastery of Moreira, which give land por que aiudastes nos “because you helped us” to claim other estates.[3][2] In Galician-Portuguese it is common from the 13th century in the senses “to help, aid, succour”: the Cantigas de Santa Maria pray that the Virgin nos dev'ajudar “must help us”, and the oath se Deus m'ajude “so help me God” is already used there.[11][4]
Semantic evolution
The medieval verb meant to help, succour and assist, and could take a direct object or the prepositions a and de.[11][12] Cunha dates ajuda and ajudador to the 13th century and ajudante to the 14th.[4]
Morais (1789) adds the senses “to serve, minister” (ajudar à missa, to serve as an acolyte at Mass) and “to promote, favour”, as in bitter things that aid digestion, and the phrase ajudar a bem morrer, to give a dying person the comforts of religion.[13] With the reflexive it meant “to make use of, avail oneself of”.[13][2]
In north-eastern Brazil the verb is a term of the sugar mills, “to add the clarifying liquid (the ajuda) to the cane juice”.[14][15] In the Alentejo the reflexive ajudar-se meant to be able to do a job, or carry a load, by oneself.[16] The verb passed into Macanese as judâ.[1]
