author
Best known for practical early-20th-century Spanish language manuals, this author focused on the kind of real-world vocabulary learners could actually use. The surviving record is sparse, but the books linked to his name point to a clear specialty in conversation, grammar, and business Spanish.

by W. N. (William N.) Cornett, C. Hossfeld
W. N. Cornett, also identified in library records as William N. Cornett, was an early-20th-century author and compiler of Spanish-language learning materials. His work is associated with titles such as Hossfeld's Spanish Dialogues, and Idiomatic Phrases Indispensible for a Rapid Acquisition of the Spanish Language, along with Spanish Commercial Correspondence and Technicalities and a supplement to an English-Spanish technological dictionary.
These books suggest a practical approach rather than a literary one. They were aimed at students, travelers, and business readers who needed usable Spanish for conversation and commerce, especially at a time when self-instruction manuals and correspondence guides were widely used.
Very little biographical information about Cornett appears to be reliably available in major public-domain and library sources consulted here. Because the personal record is so limited, he is best understood through the educational books he helped produce and revise, which kept his name in circulation long after their original publication.
