Pronunciation

Forms

acum[1] Variants: acuma, popular acu, acmu, and the regional acru and acruma.[2][3] Banat has acnu and acrum, and the regional amu is widespread.[3]

Etymology

It is inherited from Vulgar Latin *eccum modo, a compound of the deictic particle eccum (“here he is”) and modo (“just, only; now”).[3][4][5][1] The Latin adverb is the shortened ablative of modus (“measure, manner”), first “by measure, exactly”, then “only” and “just now”; in speech it lost its /d/ and became ⟨*mo⟩, as in quomodo, the source of cum.[3] DELR explains the two stresses of the Latin compound: ⟨eccúmmo(do)⟩ gave ⟨acum⟩, while ⟨eccummó(do)⟩ gave the ⟨acmo⟩ and ⟨amo⟩ of the dialects south of the Danube.[3] Candrea and Densusianu derive every Romanian form from the same compound through ⟨acmu⟩, with the stress moved under the influence of the Latin word for “how”.[4]

Ciorănescu sees a different path for the short form: ⟨acu⟩ would continue *eccum hūc, and ⟨acum⟩ a longer compound with the same parts and the adverb for “now”.[4][3] DELR also records the view that ⟨acu⟩ is simply ⟨acum⟩ worn down in speech.[3]

The adverb survives in all four branches: Aromanian amu, Megleno-Romanian cmo and Istro-Romanian acmo.[3][4][6][7] The Latin adverb lives on in Italian mo, Dalmatian mut and Sardinian immoi, and the compound with the particle also in Sardinian komo.[3][8][1]

Earliest recorded meaning

The first record is the variant acmu “now, at present” in the Psaltirea Hurmuzaki of the early 16th century.[3] Tiktin dates acum to the Codicele Voronețean of the same century.[9] Coresi's psalter of 1589 has it at Psalm 19:6.[10]

Semantic evolution

The basic sense, “now, at this moment”, has stayed the same since the first texts.[3][9] From it came “at once, immediately” and, before a measure of time, “ago”: acum doi ani “two years ago”.[5][4] The phrase acu-i acu means that the decisive moment has come.[5][9]

Romanian built a small family on the adverb: acuși “at once”, with the particle -și also seen in același “the same”, is recorded from 1562–1571, acuma from 1612 and the diminutive acușica from 1838.[3][4]
