Comparative Grammar of the French, Italian, Spanish and Portuguese Languages
My new favorite book.
Published in 1868!
400 pages of comparative goodness.
Verb conjugations (we really should bring back thou hadst and the T-V distinction in English!)
There’s even vocabulary at the end, though the words are not grouped thematically like they are in The Loom of Language.
I’ve also ordered A Comparative Practical Grammar of French, Italian and Spanish by Oliver Heatwole (1949) as well as Comprendre les langues romaines: Du français à l’espagnol, au portugais, à l’italien & au roumain by Paul Teyssier (2004), but I haven’t yet found a book like this for the Germanic languages. As soon as I can determine if Notley’s book is in the public domain (there was a reprint in 1977 by an American publisher), I will start scanning and/or re-typing it to share it online.
