alla

The Italian preposition alla collapses three Latin words into two syllables. It comes from ad illam, meaning at that or to that, with the feminine article fused to the preposition. Italian inherited from Latin the habit of contracting prepositions with their articles, producing forms like nel, della, and alla. By the 17th century, alla was carrying a specific directional meaning in musical scores: in the manner of.

When Johann Sebastian Bach wrote alla breve at the top of a score, he was using Italian as a lingua franca that had no particular connection to his German background. The term meant in the short style, with note values halved and the beat subdivided differently. Mozart's Rondo alla Turca from 1783 used the same formula to signal a stylistic imitation of Turkish military band music. Alla became a prefix for cross-cultural musical gestures.

The same preposition migrated into culinary Italian, where it functions identically: pollo alla cacciatora is chicken in the style of the hunter, pasta alla Norma invokes Bellini's 1831 opera. English cookbooks began importing these formulas in the 19th century as Italian cooking gained prestige in Britain and America. The construction was so recognizable by 1900 that restaurant menus used it without translation. Alla required no explanation because the formula itself was the explanation.

Today alla is a functional English borrowing, neither fully assimilated nor treated as foreign. Music editors write alla breve without italics; food writers say alla Norma and assume readers understand it means in the style of. The Latin thread from ad illam through the contractions of medieval Italian is invisible in daily use. What remains is the gesture: this thing is done in the manner of something else.
