Spotting cognates

A practical toolkit: suffixes, French disguises and the two layers of vocabulary.

Most of the vocabulary of the six sisters is shared, but disguised by regular changes. Learn the correspondences and every word you know becomes six. Romanian, with its large Slavic layer, shares a little less of the everyday core, but almost all of the learned vocabulary. Start with the easy wins — suffixes — then the French disguises, then the key distinction between inherited and learned words.

The circumflex is a lost s

In French, a circumflex often marks an s that was once pronounced before a consonant and later fell silent. Put the s back and the cognate appears — in Spanish, Italian, Portuguese, Catalan, often Romanian and often English (see the Sound laws: circumflex). Not every circumflex hides an s (âge, sûr, dû), but most do. The same trick works on dîner: Old French disner.

es-, é-, s-

Latin words beginning with s + consonant were hard to say for Western speakers, who added a helper vowel: Spanish, Portuguese and Catalan es-, Old French es-, which became é- when the s fell silent. Italian kept the bare s- (see the Sound laws: s-impura), and so did Romanian in the East (stea 'star'). So STATUM, SCHOLAM, STELLAM, SPATHAM give estado, escuela, estrella, espada in Spanish; estado, escola, estrela, espada in Portuguese; estat, escola, estrella, espasa in Catalan; état, école, étoile, épée in French; stato, scuola, stella, spada in Italian. French é- + consonant at the start of a word? Try es- in Spanish, Portuguese and Catalan and s- in Italian — and often s- in English: state, school, sponge (esponja, éponge, spugna).
