Pronunciation

  • Balearic, Central, Northern, Northwestern, Valencia: [ˈrat͡ʃ][1]

Forms

raig m (plural raigs or rajos)[1] The plural is raigs or rajos.[1][2] Old Catalan wrote raig, rag and ray.[3][4] Ray in the Vides de sants rosselloneses stands before a consonant and reflects the reduction of -ig before d- that colloquial speech still makes, often in Roussillon and normally in Mallorca.[3][4] Dialect forms include Ibizan ratx, Menorcan rau, from a form raio with the loss of -i- usual on that island, ral or rail with a hypercorrect -l in the Vall de Lavansa and the south of Valencia, and rayo in Valencian and Balearic texts of the 16th and 17th centuries, which Coromines puts down partly to Mozarabic.[3]

Etymology

It is inherited from Old Catalan raig, which is inherited from Latin radius (“staff; spoke of a wheel; ray of light”).[3][5][6][7][1] It is a doublet of radi, borrowed from the same Latin word.[1][6]

The same Latin word is Occitan rai, French rai, Italian raggio, Spanish rayo, Portuguese raio and Romanian rază.[8][1]

De Vaan finds the Latin word without a clear etymology.[9] He rejects the link with rādīx (“root”) proposed by Walde–Hofmann and Pokorny, since the meanings are completely different.[9]

Earliest recorded meaning

Llull's Llibre de contemplació (1272) speaks of the sun spreading its rays (rags) over plains, mountains and valleys.[4] In the Llibre del gentil he says that God gave the sun the power to pass its rays through glass without breaking it.[3][10] The first sense was thus the ray of light, as in the Vides de sants rosselloneses, where un ray devinal translates Latin radius divinitus.[3][7]

Semantic evolution

By comparison of rays of light with streams of liquid, the word was applied early to a jet of water: the Tirant describes a silver statue of a woman from whose breasts ran un raig d'aygua molt clara.[3] The cookery book of Robert de Nola (1520) calls for un raig de oli.[4] The spoke of a wheel, a Latin sense, appears in texts of the 16th and 17th centuries.[3] In the far south raig de Sant Martí is the rainbow.[3]

The DCVB records further senses: a mass of things falling or moving fast, a draught of air, a sudden attack of illness, and, in texts of little lexical purity, lightning.[5] Fabra's dictionary of 1932 defines the ray of physics and lists cathode rays, beta rays and Röntgen rays.[11]

The verb rajar is recorded in 1460, in Roig, from Latin radiare.[6] Rajolí “trickle” is recorded about 1900, in Verdaguer.[6] The learned radi entered in 1803, radiar and radiació in 1868.[6]

Usage notes

The DIEC2 heads a second noun raig meaning a raft, a variant of rai.[2] The DCVB keeps the raft in this article and relates it to Occitan a rai “in floods”, while the Consolat de Mar already speaks of a ship meeting algun raig de fusta, a raft of timber.[5][4]
