Yakov Malkiel (July 22, 1914 – April 24, 1998) was a U.S. (Russian-born) Romance etymologist and philologist. His specialty was the development of Latin words, roots, prefixes, and suffixes in modern Romance languages, particularly Spanish. He was the founder of the journal Romance Philology.
Malkiel was born in Kiev to a Russian-Jewish family, and was brought up and educated in Berlin, after the Russian Civil War. Despite an early interest in literature, he ended up studying linguistics at the Humboldt University of Berlin, then known as the Friedrich-Wilhelms-Universität. Being a Jew in 1930s Germany was an obstacle to his education, but one he was able to overcome; his family finally emigrated to the United States in 1940.
After two years unemployed in New York, Malkiel accepted a one-term appointment at the University of Wyoming in Laramie. In 1943, he was offered an initially temporary position at the University of California, Berkeley, which later was converted to a permanent professorship; Malkiel remained there until his retirement in 1983, teaching in the departments of Spanish and (later) Linguistics. He married fellow Berkeley professor María Rosa Lida de Malkiel, a philologist and literary critic from Argentina, in 1948.
During a period when etymology was receding from prominence in linguistics, Malkiel was both one of its chief champions and most rigorous theorists. Best known for his work on the role of sound in the development of suffixes, Malkiel coined the term lexical polarization to describe the influence in sound words tend to have over the development of their opposites, when antonyms occur in pairs. A major secondary interest was in the history of his field, explored in the pages of Romance Philology and in his last book, Etymology. His work in all fields was characterized by a doggedly comprehensive use of evidence; of his book, Development of the Latin Suffixes -antia and -entia in Romance Languages, influential linguist Leo Spitzer said in a review, "No one can fail to be impressed by this outstanding example of akribia and scholarly devotion to a task that might have daunted others."
